How are you? I'm really glad that you are interested in traditional Chinese festivals. There are many traditional festivals in China, such as Spring Festival, Mid-Autumn Day and so on. I'd like to introduce the Spring Festival to you. Spring Festival is the most important traditional holiday in China. It usually lasts for 15 days.
Days before the festival, people clean their houses. They think cleaning sweeps any bad luck. They decorate their houses with paper cuts. On the eve of the festival, family members get together and have big meals. Then they watch the Spring Festival Gala on TV. At midnight, they set off fireworks to welcome the New Year. During the festival, kids get lucky money from old people. People visit their relatives and friends. They wish each a happy year and good luck. How happy we are.
