It is Tomb Sweeping Day, the traditional Chinese festival to remember the dead. Tomb Sweeping Day falls on April 4 this year. On the day, Chinese families will sweep the tombs and clean away the grass around them. Then they burn paper money and put flowers and fruit in front of the tombs. They hope the dead can enjoy them and bring the family good luck. However, it is not only the Chinese who remember the dead. People in other countries also have festivals for the dead. In Japan, O-Bon festival (盂兰盆节) is one of the most important festivals. It is held from Aug 13 to 16. It is also a holiday that serves as a family reunion (团圆). During O-bon, Japanese people return to their hometown and visit their ancestors’ tombs. They also believe their ancestors’ spirits (灵魂) return home to be reunited with their family. People perform a “bon odori” dance (盆舞) to welcome the spirits. On the last day of O-bon, they put paper lanterns in a river to send off the spirits. In Russia, people remember their ancestors on the Day of Rejoicing (欣喜). It’s usually in late April or early May. The name of this festival means birth and happiness. Russians believe that people shouldn’t feel sad for the dead because death means birth in another world. On the Day of Rejoicing, Russian people draw beautiful pictures on eggs and put them in front of tombs. After that they have a picnic together. They hope for a good life for both the living and the dead.
