In China, the most impressive festival is Spring Festival.
On Spring Festival Eve, sons get back to their parents' houses with their sons and wives. Two activities are necessary for a family to celebrate Spring Festival Eve.
One is to making jiaozi. When making jiaozi, family members talk about events happened in the passing year to say goodbye to the passing year. And they will put coins in jiaozi secretly. They believe that people who get jiaozi with coins have good lucky in the coming year.
Another activity is to play firework. Ancient Chinese thought that big sound would frighten monsters away. Nowadays Chinese regard this activity as one of the most exiting and interesting moments they may share with family.
Without either of the two, Spring Festival cannot be perfect. Chinese people take family as the most important part in their lives, so they cherish Spring Festival, which provides them a chance to have family reunion.
