There is one legend that states that it was a time to worship Taiyi, the God of Heaven in ancient times. The belief was that Taiyi controlled the destiny of the human world. He had sixteen dragons at his beck and call and he decided when to inflict drought, storms, famine or pestilence upon human beings. Beginning with Qin Shi Huang, the first emperor of China, all the emperors ordered splendid ceremonies each year. The emperor would ask Taiyi to bring favorable weather and good health to him and his people.
