China’s biggest and most popular traditional festivals include:Chinese New Year/Spring FestivalEach year, between the end of winter and the beginning of spring, people throughout China enthusiastically celebrate the first traditional festival of the year, the Spring Festival or Lunar New Year. During the Spring Festival, every household will display Spring Festival couplets and pictures, and decorate the home. Spring Festival Eve is an important time for family reunions. Usually, in the evening of the last day of the twelfth month by the lunar calendar each year, the entire family gets together for a New Year’s Eve dinner. After dinner, all family members sit together to chat or play games, staying up till early the next morning. In the morning people pay New Year calls on relatives to extend congratulations. During the festival, many people also attend traditional recreational activities, such as the lion dance, dragonlantern dance and stiltwalking. Chinese New Years is by far the most wellknown Chinese holiday, and also the most significant to Chinese culture. Also known as The Spring Festival, observation of the holiday actually begins the day before the beginning of the Lunar Year. The mode of celebration varies from province to province, different areas having their own specific traditions. Listed below are some of the customs associated with New Years. The day before the Spring Festival, there is a lot of cleaning and preparation done. Offerings to the Kitchen God are monly made in hopes that he will give a good report to the Emperor of Heaven. That night is a special gathering when the whole family get together and eat a particularly large dinner. The following three or four days are public holidays. Most businesses close and time is spent paying formal visits to friends. Visitors bring a gift (generally a box of chocolate, nuts, or a tin of cookies) and are given a gift of greater value by the hosts. Married couples give little red packet envelopes to children and unmarried friends when greeted with a phrase wishing them prosperity in the New Year. While the majority of the holiday is observed in the first 3 or 4 days of the New Year, the first 10 days of the year are all part of the festival, however in practice this is just additional time to get in visits to friends. During this time, many Chinese people take trips to the city or province where they were born. Certain foods take on special names to celebrate the New Year (for example, chicken is called phoenix), visitors are often treated to fruits and seeds, and people buy new clothes. During prosperous times, entirely new furnishings may be bought. In the holiday, negative words, such as death, should be avoided. In fact, gifts of four and the word four arelso often not used because it sounds like the word for death.Lantern Festival The 15th day of the first lunar month, the first full moon after the Spring Festival, is the occasion for the Lantern Festival.
