It's better to change the mat before going to work after the Chinese New Year, but if it's a mat at home, it can be changed after the evening of the 30th 12 or in the early morning.
Chinese New Year means "New Year's Day" and now it is called "Spring Festival". The main contents of New Year greetings are to bid farewell to the old, worship ancestors, exorcise evil spirits and pray for a new year. The form is rich and colorful, lively and festive, and the annual flavor is rich, which embodies the essence of traditional culture of Chinese civilization.
