In 2020, a sudden epidemic caused the whole city of Wuhan to be closed and the whole city was put on alert. The traffic police and police are in place to take care of them, and doctors and nurses put on protective clothing and are busy in the hospital. The most important thing is that for Wuhan citizens, people inside can't get out and people outside can't get in. No one has become the norm in the streets, and people are trapped at home, expecting the news that the epidemic is over. Especially for the city of Wuhan, it should be the season of cherry blossoms, and people are ready to go to Wuhan University to enjoy cherry blossoms. But the streets are sparsely populated, and cars in twos and threes queue up to buy food. More often, it's normal to be empty, and silence fills the city. Students can't go to school, so they can only take classes online at home. Workers can't go to the office to finish their grades with their colleagues, so they can only choose to work online at home. Especially for the college entrance examination students, how much pressure they have to bear to complete this year's preparation sprint, most people are like a imprisoned bird, which can only move in a cage and can't fly around at will. Although faced with such an environment, we persisted and won the smoke-free war. However, the moment Wuhan was liberated from the city, it not only excited Wuhan people, but also excited all China people. Sparse people have become people coming and going, there are more cars on the road, children can go downstairs to play again, work everywhere is busy again, and snack bars on the street are busy again. A few months later, the city of Wuhan is finally full of vitality again. Many people in Wuhan shed tears, while many people in China shed tears. At this moment, victory belongs to us, at this moment we are free, and at this moment our motherland is great. We will always remember the day when Wuhan was unsealed and the night when we learned that the road was full of cars. I will always remember the smiling face of Wuhan people.
