(B)
You may have known about many traditional Chinese festivals such as the Spring Festival or the Lantern Festival, but have you ever heard of Dragon Heads-raising Day
Dragon Heads-raising Day is also called the Spring Dragon Festival. It is on the second day of the second lunar (农历) month. It's on February 21st this year. It came from an old story. After that day, the Dragon King will wake up from his winter sleep and bring more rain. So that day is the start of spring and farming season.
One of the most interesting things related to the day is about haircut. People believe that a haircut during the first lunar month is not a good idea. It may bring bad things to your uncles. So people can only cut it on or after Dragon Heads-raising Day. Although it's not true, many people still do it.
There are also other ways to celebrate this festival. For example, people eat food with dragon names. People call noodles dragon's beard (胡须). Dumplings are dragon's ears and spring rolls (春卷) are dragon's scales (鳞).
People also do dragon dances and make dragon lanterns. The lanterns stand for people's best wishes and good luck.
