"Worship the church" is also called "worship heaven and earth" or "worship flowers and candles". This custom originated from the story of Fuxi Nuwa brother and sister getting married. At that time, there was no matchmaker, only heaven and earth as evidence, which led to marriage and human reproduction. Therefore, future generations should worship heaven and earth when they get married, indicating that this marriage is a match made in heaven, with heaven and earth as evidence, so it will also be protected by heaven and earth. In fact, the "Six Rites" ordered by the Duke of Zhou did not include the section of bowing to the court. It is generally believed that this is a kind of etiquette that arose after the Northern Dynasties, which originated from the northern minorities and then evolved from the Han nationality. Tang sealed the performance of "Feng's Experience" and said, "In modern times, there were obstacles, husbands, fans, flowers and candles, accounts in Tanaka, and ceremonies to pay homage to the church. This is true from the royal family to the literati. " It can be seen that the custom of worshipping the church was very popular in the Tang Dynasty.
