April 4th is the Tomb-sweeping Day in China, which is one of the most important traditional festivals. The young people will come back home and sweep tomb with their families. The meaning of Tomb-sweeping Day is to honor the ancestors and it has more than 2500 years' history. Chinese people pay special attention to remember their ancestors, so no matter how far they are, they always know where they are from. When they are old, they will return to the place where they are from. It is a good tradition. The sense of belonging makes people feel safe. What's more, the relationship between relatives makes the whole family become stronger, because people are united by the same ancestors. Thus, they treat each other as families and give support all the time. What a great tradition it is.
