On January 17, the annual Spring Festival transportation kicked off. According to the comprehensive prediction of the transportation department, it is expected that 1.18 billion passengers will be sent nationwide during the Spring Festival transportation this year, with an average of 29.5 million passengers per day. Although this figure was significantly lower than that before the epidemic, it increased by 35.6% compared with the same period last year - another big test for the transportation industry under the normalization of epidemic prevention and control. As the new year approaches, people who have been busy in a foreign country for a year, as usual, begin to plan the arrangements for returning home for the new year. Before the outbreak of the epidemic, the Spring Festival transportation was known as the "largest periodic migration activity in human history", which often means billions of passengers. However, since the outbreak of the epidemic, the scale of personnel flow has decreased significantly, and the number of passengers has changed from "billions" to "billions". Nevertheless, people's way back home for the new year is still full of uncertainty. The uncertainty of returning home during the Spring Festival is rooted in the uncertainty of the epidemic situation. Although compared with the beginning of the outbreak, we have mastered many regular cognition of epidemic prevention and control, and so far China's prevention and control strategies have also achieved remarkable results, as scientists admit, we still "know very little" about this cunning virus, and the continuous variation of virus strains often refreshes people's cognition of its transmission and attack. In addition, with the opening of Beijing 2022 Winter Olympic Games and winter Paralympic Games, the transportation industry will face the dual pressure and challenges of "Olympic Games" and "spring transportation". Two days ago, a newly diagnosed patient in Haidian, Beijing, immediately attracted widespread attention. In this critical period of superposition of "Olympic Games" and "spring transportation", the epidemic dynamics of each city will be closely related to the Spring Festival holiday schedule of a considerable number of people, and the epidemic prevention and control situation in Beijing is directly related to the Olympic event. After screening the confirmed case, Beijing quickly took a series of measures to close the transfer cases, screen the close contacts, inform the relevant situation and identify the source of infection. After more than two years of fighting against the virus, people have gradually realized the true meaning of "coordinating epidemic prevention and control and economic and social development". Maintaining normal economic and social order is one of the purposes of implementing the epidemic prevention and control strategies of "external defense input, internal defense rebound" and "dynamic clearing". Under the principle of scientific prevention and control and precise prevention and control, we will organize a regular epidemic prevention and control network, orderly connect the diversified transportation connections of Spring Festival transportation, and plan emergency plans in advance for various emergencies, so that foreigners who choose to "celebrate the new year on the spot" can feel the tolerance and warmth of the city, and so that "migrant workers" who have been wandering for two or three years can smoothly return home and reunite with their families. To minimize the impact of the uncertainty of the epidemic situation on people returning home for the new year, we must also attach great importance to the timeliness and effectiveness of the epidemic situation and the release of prevention and control policies. At present, there are more than ten days before the Spring Festival, most of the students who plan to return home have returned home. The main passenger flow before the festival is the returning migrant workers. All localities should timely release the local epidemic dynamics and return policy requirements to minimize the negative impact of the temporary adjustment policy. For some areas where labor inflow and outflow are concentrated, we can also explore the organization of passenger transport in the form of point-to-point charter to reduce the risk of virus transmission. "At the end of the year, thousands of miles have not returned." From home to abroad, the Spring Festival reunion carries the cultural complex of the Chinese people for thousands of years. Novel coronavirus pneumonia has been seen in the long years, and has also experienced the difficult times like the new crown pneumonia epidemic. It eventually precipitated the unique cultural spirit and festival ritual of the Chinese nation. No matter whether the Spring Festival can go home or not, this concern for the family, the expectation of reunion and the blessing to the family and country are always like the Millennium full moon, shining in the spirit of every Chinese.
