Every year, the second day of the second month on the Chinese lunar calendar is regarded the birthday of the God of Earth. The first day and the fifteenth day, or the second day and the sixteenth day of every month of the lunar calendar are the monthly sacrifice day. Every 16th day of the 12th month of the lunar calendar is the sacrifice day of the "year-end dinner". Folk activities include the ceremony to light the first incense to invite the ruler of heaven, holding the sacrifice ceremony, sending stoves, and offering incenses to Buddha. Among these activities, meeting the deities, dancing performances, and opera performed to show gratitude for gods are all cultural events.
