Why do migrant workers have to go home during the Spring Festival?

Migrant workers, why do you want to go home during the Spring Festival? There is only one reason. That is to reunite with your long-lost family. People in China pay attention to having a reunion dinner in the reunion year. Migrant workers have been working hard in other places for a year. At this time of Spring Festival reunion, they should go back to their hometown, their families, their children, have dinner with everyone, and let everyone get together for a happy New Year. Only after the festival will they be very energetic.
