Through the ocean tunnel and in close contact with the fish, children in distress can enjoy a healing journey in the quiet underwater world. This summer, the Pacific Ocean World Expo, located in Haidian District, Beijing, held a special visit for children with autism in the city. "When the city helps enterprises solve difficulties, we should also give back to the society in a timely manner!" Zhou manager of the Finance Department of the Expo said gratefully. The reason why manager Zhou is grateful can be traced back to a few months ago. Affected by the epidemic, from the end of April to the beginning of June, all indoor venues in the city's scenic spots, including the Pacific Ocean World Expo, were temporarily closed. "The museum was closed as soon as the peak tourism season arrived. The capital accumulation in the off-season simply could not bear the daily labor, water and electricity, social security and other operating costs." Looking at the fish pond that used to be full of spectators, manager Zhou was at a loss. "The income of the Expo Hall mainly comes from tourists' tickets. Now, the funds for changing the water for the fish are almost insufficient." The operating difficulties of the Pacific Ocean World Expo are also the difficulties that many enterprises will face in the epidemic, and are also the "problem orientation" of the city's discipline inspection and supervision organizations at all levels to supervise and escort the "economic stability". In the list of key supervision and inspection tasks of "stabilizing the economy" sorted out by the Municipal Commission for Discipline Inspection and supervision, the first item is "a package of policies and measures for coordinating epidemic prevention and control and stabilizing economic growth" According to the work deployment of the Municipal Commission for Discipline Inspection and supervision, the Commission for Discipline Inspection and supervision of Haidian District has formulated the work plan on strengthening the supervision of the key tasks of coordinating epidemic prevention and control and economic and social development. By using advanced technologies such as blockchain and big data computing, it has conducted intelligent screening and data comparison on the work order content of 12345 citizen service hotline, accurately discovered and understood the difficulties of enterprises, and predicted that formalism The key points of bureaucracy require the relevant post offices to strengthen the "probe" role, and implement "double supervision" through grasping the epidemic prevention and control and preferential enterprise policies to ensure that the epidemic is not "out of control" and development is not "stalled". "How can we fully understand the preferential policies for enterprises?" Yu Wen, a cadre of the discipline inspection and supervision group of the human resources and Social Security Bureau in the District, and the team members visited the social security center in the district on the spot to understand the key links such as the coverage of the policy, the period of deferred payment, the application conditions, and the handling process. In view of the data source, feedback mechanism and other contents as well as the problems existing in the work process, the group formulated a list of problems and proposed to further expand the awareness rate of preferential policies for enterprises and ensure that they should enjoy the benefits. With the promotion of a series of preferential policies for enterprises in Haidian District, the management problems faced by the Pacific Ocean World Expo Center have been solved. "It's unexpected that 'policy living water' is directly injected into the 'pool' of the aquarium through the network!" On May 9, manager Zhou saw on the wechat official account of Beijing Haidian social security center the notice on the phased implementation of deferral of payment of basic old-age insurance, unemployment insurance and industrial injury insurance premiums for employees of catering, retail, tourism, civil aviation, highway and railway transportation enterprises, and immediately applied online according to the process published in "policy interpretation of dry goods". "From April, the Expo Hall can enjoy the 'deferred' policy of social insurance premiums for old-age, unemployment and industrial injury", manager Zhou sighed with relief. It is reported that on June 2, the Beijing Municipal People's government issued a notice on
