It’s a traditional festival in china. It comes in winter.
It’s time to get new. We usually clean and decorate our houses carefully before it comes. I always help my mother clean the windows and wash the clothes. We put on Chunlian on the doors and chuanghua on the windows.
It’s time to say goodbye to the last year, and say hello to the New Year. Everyone goes home to get together with their families, no matter how far it is. They must have dinner together on that day. They must visit their relatives and friends and say “Happy New Year” to them. When the kids greet their grandparents, they can get money.
