Chinese love to celebrate festivals. There are plenty of festivals throughout a year. Most of them are based on lunisolar calendar, which divides a year to 24 solar terms. For example, you probably don’t want to hang out at night on 4 April or 5 April, as it’s Qingming festival, known as tomb-sweeping day. It is believed that all the death and evil spirits will return on this day. People normally go visiting the graves of their ancestors with food, drinks and flowers. Therefore it is not considered a good day to conduct business. Other festivals like mid-autumn festival, double-seven festival(Chinese valentine’s day), lantern festival and dragon-boat festival are commonly celebrated by the Chinese.
