Adhere to the problem-oriented principle, strictly check the public funds, eat and drink, and severely curb the waste of unhealthy food and beverage, which is not a trivial matter. It is related to national food security, social ethics, and the cultivation of good style. The report of the Twentieth National Congress of the Communist Party of China emphasized that we should implement the comprehensive saving strategy, promote the conservation and intensive use of various resources, promote the formation of green and low-carbon production and lifestyle, and advocate green and low-carbon, comprehensive saving. Discipline inspection and supervision organs at all levels should deeply understand the spiritual essence and practical requirements of the "comprehensive saving strategy" in food security, put the rectification of food and beverage waste in a more prominent position, constantly make unremitting and comprehensive efforts to implement policies, guide social customs and customs with good party conduct, and promote the formation of a good practice of practicing economy and combating waste in the whole society. Compacting responsibilities layer by layer and promoting the joint management of one porridge and one meal is not easy. On April 29, 2021, the 28th meeting of the Standing Committee of the 13th National People's Congress passed the Law of the People's Republic of China on Combating Food Waste. On October 18 of the same year, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council issued the "Action Plan for Food Conservation". The whole party resolutely implemented various economic measures, took the lead in practicing economy, and opposed waste. Discipline inspection and supervision organs at all levels firmly implement the decision and deployment of the Party Central Committee, put the rectification and treatment of food waste in a more prominent position, urge the compaction of responsibilities at all levels, put a stop to extravagance and waste, promote the establishment of a long-term mechanism, promote joint management, and resolutely curb "waste on the tip of the tongue". We should attach great importance to it in thought and grasp it in action. Based on post responsibilities, supervise and urge compaction responsibilities. The Shaanxi Provincial Commission for Discipline Inspection and Supervision took the performance of the relevant functional departments to stop food waste as the key point of supervision, and issued the Work Guidance on Strengthening Special Supervision over Food Saving and Preventing Food Waste, focusing on the performance of the duties of 10 functional departments to stop food waste, clarifying 21 key contents, and promoting the implementation of regulatory responsibilities. Focusing on the main responsibility of style construction, the discipline inspection and supervision team of China Southern Power Grid Corporation assisted in urging the company's party group to study and put forward a series of specific measures to prevent food and beverage waste, which were integrated into the company's overall deployment of "tight living" and promoting cost reduction and efficiency increase. Adhere to the problem-oriented principle, stick to the continuous efforts of all regions and departments at one node. The problem of public spending and extravagance has been effectively curbed, and the good atmosphere of shameful waste and glorious saving in the whole society has been constantly strengthened. However, there are still a few Party members and cadres whose ideological foundation of practicing economy is not solid, their behavior inertia has not been completely reversed, and problems such as over-standard meals in official activities, false spending and taking public funds to eat and drink have occurred from time to time. Discipline inspection and supervision organs at all levels adhere to the problem-oriented principle
