How does the Temple of Heaven worship heaven?

Among the sacrificial activities held in the Temple of Heaven, the winter solstice is the biggest in Zhangqiu. The emperor offered sacrifices, fasted before the sacrifice, and personally watched the sacrifice the next day to show his respect. During the sacrificial ceremony, various ceremonies are performed, such as welcoming the gods, offering jade and silk, entering the tomb, saying greetings, offering three products, receiving blessings, seeing off the gods, watching meteors and so on. The emperor led hundreds of officials to kneel and knock. The ceremony was complicated, solemn and grand. Another sacrificial activity held in Huaqiu is a regular ceremony held in Xia Meng season. The routine ceremony is a rain prayer ceremony. Praying for rain can be divided into two types: routine ceremony and grand ceremony. Under normal circumstances, Xia Meng prayed for rain in Cooper in Waqiu every year, which is a routine ceremony. But it often doesn't rain after the ceremony, and the emperor sends officials to worship gods, goddesses, ancestral temples, countries and other gods every seven days. If it doesn't rain after three reports, a big ceremony will be held. At that time, the emperor went to the ball to pray, without setting a halogen book, destroying the Tao, having fun, coordinating, offering jade and silk, and drinking blessings. Three gifts are 16 dancers, wearing mysterious clothes. Yu Yi is the same as Chang Yi. If it rains, you need to report "thank you for the rain". Pray for more rain and hold a prayer ceremony for sunny days. When it clears up, it will be called "Xie Qing". Meng Chun worships the valley on a new day, and it is held on the altar to pray for the valley. The ceremony is the same as worshipping heaven in the dome. The word "nian" in "Hall of Praying for the Year" originally meant "uncle", that is, praying for a bumper harvest year from God.
