Xinhua Media | The Warmth of a Bowl of Noodles

Xinhua Media | The Warmth of a Bowl of Noodles Xinhua News Agency, Taiyuan, October 26 (Reporter Wang Feifei, Chai Ting, Ma Xiaojie) On Caiyuan Street in Yingze District, Taiyuan City, Shanxi Province, there is a noodle shop called Laojunying for marinated noodles. Over the past six years, this noodle shop has not only provided sanitation workers with free and unlimited warm meals, but also one warm story after another. At 4 o'clock in the morning, the bleak autumn wind blew off the leaves, and sanitation worker Wang Shuwei had already started the cleaning operation. "It's colder today. The ground is frozen hard." After whispering a few words, he waved his broom and continued sweeping. After finishing the morning cleaning, it was already 7 o'clock in the morning, the temperature was still very low, and the sweat-soaked clothes were blown by the cold wind, which made Wang Shuwei's body a little cold. At this time, the old barracks marinade noodle hall also opened the door, and the boss Yao Xiaorui called Wang Shuwei to enter for a hot meal. After a bowl of hot noodles, Wang Shuwei felt warm. According to Yao Xiaolui's recollection, Wang Shuwei was very shy and was embarrassed to enter the store at first, so he had to give him the noodles out and then dragged him into the store. "It's cold outside, and the noodles are cold before they are finished." Yao Xiaorui said. Yao Xiaorui, 57, and his wife, Wang Linzhen, were laid-off workers. In 2006, the thoughtful couple decided to open a restaurant. "We will make marinated noodles, and our relatives and friends say that we have done a good job, so we have started this business." Yao Xiaorui said. The hardships of opening a shop made the couple more aware of the difficulty of life, and also gave them the idea of helping others. Seeing that the sanitation workers outside the door were tired and could only sit on the steps of the door for a while in the cold wind, Yao Xiaolui volunteered to invite them in to warm up. At first, he poured a cup of hot water, and then he began to provide free marinated noodles for the sanitation workers nearby. On October 21, sanitation worker Zhu Qiangen helped throw out the garbage after eating the marinated noodles. Photo by Xinhua News Agency reporter Chai Ting "At first, they were very restrained and felt embarrassed to eat for free. I left some work for them to do so that they felt better." Yao Xiaorui said, slowly, often come here to eat six or seven sanitation workers always see what work to help do, choose vegetables, clean the table, take out the garbage... years get along, we have become a mutual help family. "I don't think your pot is too good. I guess it's still an old problem. I'll fix it for you and it will last for a few more months." Ma Xiwang, a sanitation worker, has the ability to repair pots. When he sees that there are often problems with the rice cooker in the noodle shop, he always takes the initiative to help repair it. In the past six years, Ma Xiwang has repaired four or five electric rice cookers for the noodle shop. "Save us a lot of money." Wang Linzhen said with a smile. Yao Xiaorui and his wife are particularly keen on the business of the noodle shop. Although the shop is not large, they tidy up the shop every day. In order to reassure customers, they washed vegetables over and over again. Sanitation worker Zhao Haiqiao saw in his eyes that he would come to help choose and wash vegetables in his spare time. "I washed my hands several times before, which is more serious than washing vegetables in my own home." Zhao Haiqiao said that Yao Xiaorui's husband and wife were very warm-hearted and felt very comfortable eating here. Seeing that they were too busy, they were willing to help. During the interview, the reporter found that almost every sanitation worker carried one or two bags of garbage in his hand when he left after eating. "The noodle shop has a lot of kitchen waste. Thanks to their help, the waste can be disposed of in time." Wang Linzhen said. "When you are busy, you can't help but come in and take a bite and leave." Sanitation worker Chang Hongmei said that every time at this time, the boss's mother, Wang Linzhen, would make hot water and hand it to her, telling her to get busy and leave it alone. Family-like communication makes Chang Hongmei, who works in a foreign land, feel warm. On October 21, sanitation worker Chang Hongmei greeted her with a smile with a hot water cup handed to her by Wang Linzhen. Photo by Xinhua News Agency reporter Chai Ting Once, Yao Xiaorui's father was hospitalized. He had to take care of his sick old father while running a noodle shop. After Ma Xiwang's wife heard about it, she took the initiative to help Yao Xiaorui take care of the old man. "I really appreciate the Ma family. I didn't expect that a bowl of noodles could be exchanged for so many friends. Everyone understands and takes care of each other." Yao Xiaorui said. Give me a peach and give me Qiong Yao. In the past six years, the noodle shop has sent more than 20000 bowls of noodles to the sanitation workers, and the sanitation workers have silently done what they can for the noodle shop. "As long as I can do it, I will keep this noodle shop open. Even if I retire one day in the future, I will let my son continue to do it." Yao Xiaorui said, because here has become a big family.

China's strong economic resilience adds confidence to the world

China's strong economic resilience adds confidence to the world (Wanghailou) In the past two days, China's economic "three quarterly reports" have attracted much attention at home and abroad: "China's gross domestic product (GDP) grew 3.9 year-on-year in the third quarter, significantly higher than the previous value" "Industrial production exceeded expectations, and the growth rate of industrial added value above designated size in the third quarter was 4.1 percentage points faster than in the second quarter" "This marks a strong rebound in China's economy" ...... China's economy, which has been praised by the international community. At present, the global economy is full of challenges, the new coronary pneumonia epidemic has been repeatedly delayed, geopolitical conflicts have intensified, food and energy problems have been highlighted, and the risk of stagflation is rising. International institutions such as the International Monetary Fund and the World Bank have recently lowered their global economic growth forecasts, warning that "the global economy is approaching recession". In this context, China's economy overcame the adverse effects of multiple unexpected shocks, and recovered to the better in the third quarter, which was significantly better than in the second quarter. Positive factors accumulated and increased, showing strong resilience, increasing confidence and momentum for the recovery of the troubled world economy. Resilience, based on policy is strong, the market has potential. From 0.4 percent in the second quarter to 3.9 percent in the third quarter, how did China's economy return to growth beyond expectations? Strong and effective macro policies are an important support. From the manufacturing industry, small and medium-sized enterprises, individual industrial and commercial households to extend the tax repayment period, to invigorate the more than 500 billion yuan special debt local balance limit to stabilize investment ...... With the steady economic policy package continued to exert force, the succession policy decisively launched, industry, services and other major economic indicators continue to recover. In the face of the impact of unexpected factors, China's economy has stabilized and rebounded in a relatively short period of time, which is also based on the advantage of the super-large-scale market. In the third quarter, the contribution rate of final consumption expenditure to economic growth reached 52.4, driving GDP growth by 2.1 percentage points, accelerating the release of domestic demand potential, and further strengthening the stamina of China's economic recovery and development. Resilience lies in increased economic vitality and strong development momentum. To observe the economy of a big country, we should look at the "potential" of data changes, but also the "ability" behind the development ". In the "three quarterly reports" of China's economy, a set of data is very eye-catching: in the first three quarters, the added value of high-tech manufacturing above scale increased by 8.5 compared with the same period last year, 4.6 percentage points higher than that of all regulated industries; investment in high-tech services increased by 13.4, 9.5 percentage points higher than that of all services; online retail sales of physical goods increased by 6.1, significantly faster than the total retail sales of consumer goods. These data are associated with a set of hot words-new technologies, new formats, new models and new demands. "Super Virtual Factory" has become a good helper for enterprises to tap production potential. Flexible production lines have enabled traditional manufacturing enterprises to move towards high-end customized production-the integration of cutting-edge technology with industrial and service industry scenarios has accelerated, and the quality of China's economic development has continued to improve. Resilience is conducive to enjoying China's opportunities and promoting common development. "You can always trust China." Chinese Foreign Ministry spokesperson Hua Chunying recently posted such a sentence on social media and accompanied it with a calculation chart of the World Bank's World Development Indicators Database: From 2013 to 2021, China's average contribution to world economic growth reached 38.6.%, more than the combined contribution rate of the Group of Seven (G7) countries. In this regard, some netizens commented "look, this is China's contribution". Practice has fully proved that China's economic development is not only beneficial to itself, but also to the world. Judging from the "three quarterly reports", despite multiple difficulties and challenges, China's economic development is still at a good level among major economies, and China is still an important stabilizer and power source for world economic growth. China has also continued to promote a high level of opening up to the outside world, insisting on holding international exhibitions such as the CIIE, Canton Fair, Service Trade Fair, and Consumer Fair, and actively sharing development dividends with the world. Antonio Mayori, a professor at the Free University of International Social Sciences in Italy, believes that the current world economic recovery is more fragile, and the continued recovery of the Chinese economy will have a positive impact on the world economy. China's economy is a sea. After repeated storms, China's economy has shown strong resilience and great potential, and has become stronger after the storm. With the in-depth study and implementation of the spirit of the Party's 20th National Congress, with the effectiveness of efficient and coordinated epidemic prevention and control and economic and social development and the release of macro-policy effects, China's economic resilience will be further enhanced, and China's new development will continue to contribute more positive energy to the global economic recovery. window.uuid = "892270648ddacff2346640383161754d "; window.pageCheck = "1666851878|957db99ff5673dd333184f270c0a0f5e "; window.guestuid = "892270648ddacff2346640383161754d "; window.sign = "360_c109fef1" || "look "; window.djsource = ""; window.rawurl = 'http://zm.news.so.com/2473fabdc4c769818665f0f503855154' || ''; window.whoami = 'pure_detail' || ''; window.gnid = '940aadb7ef14f2683 '; window.__INITIAL_DATA__ = {"result":{"Detail":{"category":"economy","content ":"<p>\u3000\u3000\u8fd9\u4e24\u5929\uff0c\u4e2d\u56fd\u7ecf\u6d4e\u201c\u4e09\u5b63\u62a5\u201d\u5728\u6d77\u5185\u5916\u5907\u53d7\u5173\u6ce8\uff1a\u201c\u4e09\u5b63\u5ea6\u4e2d\u56fd\u56fd\u5185\u751f\u4ea7\u603b\u503c\uff08GDP\uff09\u540c\u6bd4\u589e\u957f3.9%\uff0c\u5927\u5e45\u9ad8\u4e8e\u524d\u503c\u201d\u201c\u5de5\u4e1a\u751f\u4ea7\u8d85\u9884\u671f\uff0c\u4e09\u5b63\u5ea6\u89c4\u6a21\u4ee5\u4e0a\u5de5\u4e1a\u589e\u52a0\u503c\u589e\u901f\u6bd4\u4e8c\u5b63\u5ea6\u52a0\u5feb4.1\u4e2a\u767e\u5206\u70b9\u201d\u201c\u8fd9\u6807\u5fd7\u7740\u4e2d\u56fd\u7ecf\u6d4e\u5f3a\u52b2\u53cd\u5f39\u201d\u2026\u2026\u9876\u4f4f\u538b\u529b\u6301\u7eed\u6062\u590d\u7684\u4e2d\u56fd\u7ecf\u6d4e\uff0c\u53d7\u5230\u56fd\u9645\u793e\u4f1a\u70b9\u8d5e\u3002<\/p><p>\u3000\u3000\u5f53\u524d\uff0c\u5168\u7403\u7ecf\u6d4e\u5145\u6ee1\u6311\u6218\uff0c\u65b0\u51a0\u80ba\u708e\u75ab\u60c5\u53cd\u590d\u5ef6\u5b95\uff0c\u5730\u7f18\u51b2\u7a81\u52a0\u5267\uff0c\u7cae\u98df\u80fd\u6e90\u95ee\u9898\u7a81\u51fa\uff0c\u6ede\u80c0\u98ce\u9669\u4e0d\u65ad\u4e0a\u5347\u3002\u56fd\u9645\u8d27\u5e01\u57fa\u91d1\u7ec4\u7ec7\u3001\u4e16\u754c\u94f6\u884c\u7b49\u56fd\u9645\u673a\u6784\u8fd1\u671f\u63a5\u8fde\u4e0b\u8c03\u5168\u7403\u7ecf\u6d4e\u589e\u957f\u9884\u671f\uff0c\u8b66\u544a\u201c\u5168\u7403\u7ecf\u6d4e\u6b63\u903c\u8fd1\u8870\u9000\u201d\u3002\u5728\u6b64\u80cc\u666f\u4e0b\uff0c\u4e2d\u56fd\u7ecf\u6d4e\u514b\u670d\u591a\u91cd\u8d85\u9884\u671f\u51b2\u51fb\u7684\u4e0d\u5229\u5f71\u54cd\uff0c\u4e09\u5b63\u5ea6\u6062\u590d\u5411\u597d\uff0c\u660e\u663e\u597d\u4e8e\u4e8c\u5b63\u5ea6\uff0c\u79ef\u6781\u56e0\u7d20\u7d2f\u79ef\u589e\u591a\uff0c\u5c55\u73b0\u51fa\u5f3a\u52b2\u97e7\u6027\uff0c\u4e3a\u590d\u82cf\u9677\u5165\u56f0\u5883\u7684\u4e16\u754c\u7ecf\u6d4e\u589e\u4fe1\u5fc3\u3001\u6dfb\u52a8\u80fd\u3002<\/p><p>\u3000\u3000\u97e7\u6027\uff0c\u57fa\u4e8e\u653f\u7b56\u5f88\u7ed9\u529b\u3001\u5e02\u573a\u6709\u6f5c\u529b\u3002\u4ece\u4e8c\u5b63\u5ea6\u76840.4%\u5230\u4e09\u5b63\u5ea6\u76843.9%\uff0c\u4e2d\u56fd\u7ecf\u6d4e\u4f55\u4ee5\u5b9e\u73b0\u8d85\u9884\u671f\u6062\u590d\u589e\u957f\uff1f\u6709\u529b\u6709\u6548\u7684\u5b8f\u89c2\u653f\u7b56\u662f\u91cd\u8981\u652f\u6491\u3002\u4ece\u5bf9\u5236\u9020\u4e1a\u4e2d\u5c0f\u5fae\u4f01\u4e1a\u3001\u4e2a\u4f53\u5de5\u5546\u6237\u7f13\u7a0e\u8865\u7f34\u671f\u9650\u518d\u5ef6\u957f\uff0c\u5230\u76d8\u6d3b5000\u591a\u4ebf\u5143\u4e13\u9879\u503a\u5730\u65b9\u7ed3\u5b58\u9650\u989d\u7a33\u6295\u8d44\u2026\u2026\u968f\u7740\u7a33\u7ecf\u6d4e\u4e00\u63fd\u5b50\u653f\u7b56\u6301\u7eed\u53d1\u529b\u3001\u63a5\u7eed\u653f\u7b56\u679c\u65ad\u63a8\u51fa\uff0c\u5de5\u4e1a\u3001\u670d\u52a1\u4e1a\u7b49\u4e3b\u8981\u7ecf\u6d4e\u6307\u6807\u4e0d\u65ad\u6062\u590d\u3002\u9762\u5bf9\u8d85\u9884\u671f\u56e0\u7d20\u51b2\u51fb\u5f71\u54cd\uff0c\u4e2d\u56fd\u7ecf\u6d4e\u5728\u8f83\u77ed\u65f6\u95f4\u5185\u4f01\u7a33\u56de\u5347\uff0c\u8fd8\u57fa\u4e8e\u8d85\u5927\u89c4\u6a21\u5e02\u573a\u4f18\u52bf\u3002\u4e09\u5b63\u5ea6\uff0c\u6700\u7ec8\u6d88\u8d39\u652f\u51fa\u5bf9\u7ecf\u6d4e\u589e\u957f\u8d21\u732e\u7387\u8fbe\u523052.4%\uff0c\u62c9\u52a8GDP</p></p></p>

Problems of Highway Maintenance Machinery

Problems of Highway Maintenance Machinery After years of large-scale construction, China's highway network has been basically formed, is about to enter a high tide of highway maintenance and repair. At the same time, the increasingly heavy traffic pressure puts forward higher requirements for the efficiency and quality of highway maintenance. These favorable factors will promote the development of highway maintenance machinery, and the concept of long-term "reconstruction and light maintenance" has led to the backward level of highway maintenance mechanization in China, so the future development space is huge and the market prospect is broad. Although the road maintenance machinery industry has made great progress, but the existing problems are also prominent, especially in the era of road maintenance, and the contradiction between the market demand is increasing. Specifically, the road maintenance machinery industry mainly has the following three major problems. 1, the industry foundation is weak, insufficient research and development. China's highway construction started late, the research on highway maintenance technology is not enough attention, most of the existing maintenance technology is introduced from abroad in recent years, therefore, the industry as a whole the original innovation ability is insufficient, advanced maintenance equipment is still mostly supplied by foreign manufacturers. 2. The industry has a high technical threshold, a long product promotion cycle, and the products also have the characteristics of multi-variety, small batch and customized production. Therefore, some large domestic construction machinery companies with research and development capabilities are currently unwilling to intervene. This also leads to the domestic enterprises engaged in the industry is generally small, research and development capacity and investment is insufficient, compared with similar foreign enterprises in product reliability and advanced there is still a gap, some of the technology and products in the country is still in the blank. 3, the industry standard system is not perfect. The standard system in the industry is not yet sound and perfect, and the basic standards that have a guiding role for the entire industry are still relatively scarce, which is not conducive to the rapid and healthy development of the industry.

Why is it necessary to clean the grinding discs after curing and repairing with a floor grinder?

During floor grinding operations, it’s essential to thoroughly clean the worn-down grinding discs after each pass. This prevents sand and grit trapped inside the discs from causing irreparable scratches on the floor during subsequent work—especially critical when applying curing treatments. After repairing the surface, be sure to promptly remove any residual repair compounds or materials from the discs, as leaving them behind can make cleanup extremely difficult once they’ve fully dried. As a dust-free construction technique specifically designed for curing floor applications, this method requires careful attention. If you’re using the “grinding method” to apply repair agents or mortar, the discs will inevitably pick up these materials during the process. Failing to clean them immediately could lead to permanent damage to the floor, potentially making repairs impossible—or at least requiring significantly more time and effort. Therefore, always remember to inspect and clean the metal grinding discs after completing the curing and repair stages, particularly when employing the grinding technique. For high-quality, suitable products tailored to your needs, turn to the Metenqi grinding machines manufactured by Guangzhou Qingqinyu Environmental Technology Co., Ltd.
