The nine-day Spring Festival holiday allows busy workers to have a long vacation, meet with friends and family - reunions, New Year's greetings, trips, spring walks, playing waste, and enjoying a rare vacation with ease. At the end of the vacation, everyone adjusts their inner mood and work schedule and returns to work. This year's winter was particularly cold, and many of the warm clothes that had been put away in the corners of the closet came out one after another, but even so, they could not withstand the cold weather; the cold, coupled with the flu, and due to the group gathering, the physical condition of the people was very bad.
