There are twelve months in a year. I like February best. February is the second month of the year. In China, Spring Festival is usually in January and February. It’s my favourite festival. Now people call it Chinese New Year. For Chinese New Year, all people in China have a holiday. They go back home to celebrate the festival with their families. On the eve of the festival, people usually have dumplings. People in the south of China have rice cakes. They all enjoy the festival at home.
