The Song Dynasty was the heyday of Tang Ming etiquette in ancient China. Since late, the rural system of "three-year-old and one-parent" in Song Renzong in Song Dynasty has been formed and perfected, and the system has been fixed. The emperor personally held a public sacrifice in Blackburn or Tang Ming every three years. During the 300 years of the Song Dynasty, 48 Tang Ming ceremonies were held, which is a unique phenomenon in the ancient history of China. Gradually, what was built during the Tang Ming period was the most Confucian quadrangle in the history of China. However, Tang Ming was not the standard of the Ming Tang ceremony, and the Tang Ming ceremony in the Southern Song Dynasty was mostly held in the Qing Temple. In the Northern Song Dynasty, the Tang and Ming Dynasties served as gifts, and Changli implemented the system of strict father examination, which was shared by the heavenly father. In the Southern Song Dynasty, Changli practiced the system of matching ancestors with Japanese, and Song Guangzong was matched by Song Taiwei before the dynasty, and then by Song Taiwei. The system of giving and paying salaries in the Southern Song Dynasty has changed in many years. Two years ago, the idealistic Pope of Chunyou gave Zhao Kuangyin his salary system. Two years later, the strict father-plus-the-same system was adopted for the religious gifts of Chunyou Neo-Confucianism, with Zhao Kuangyin as the ancestor and Yuko as the father of Song Sansheng, or Yu, Taixu and Gao Zongjia as the father and Yuko as the model. In the practice of ritual system in the Song Dynasty, there appeared three debates about the system of ritual system sharing. The three debates were respectively from the system of ritual with the sky, the system of ancestor strict father's preparation, and the system of examination with father and ancestor, which reflected the inheritance and timely change of ritual system in the Song Dynasty to ancient etiquette in China. Tang Ming implemented the system of forgiveness and reward in Song Dynasty. In Song Dynasty, Tang Ming's gifts were military reward, Guan Bai, clan relatives, wives and concubines, and he pardoned the criminals in Taijuanmian and stayed there. This is an important system of gifts since the Tang Dynasty, especially in the Song Dynasty, and it is an important embodiment of the outstanding characteristics of secularization of gifts, which has had a wide impact on the society of the Song Dynasty. Tang Ming's ceremonial state flourished in Song Dynasty because of the following reasons: First, Tang Ming's gift-giving was a festival of blessing, which was conducive to declaring the legitimacy of the regime and maintaining the rule. Second, Tang Ming's talent can be changed in time to meet the needs of the society at that time. Thirdly, the study of Tang Ming's etiquette theory in Song Dynasty is rich, which provides a theoretical basis for the etiquette practice in Tang Ming in Song Dynasty. Fourth, the Tang Ming ceremony is simple and feasible. Whether in theory or in practice, Tang Ming etiquette in Song Dynasty is the development of Tang Ming etiquette in ancient China. The implementation of the system of forgiveness and reward in Song Dynasty is conducive to coordinating the contradictions among all social strata. The stability of the regime. Tang Ming's big gifts were held frequently in Song Dynasty, which increased the burden of the people and the Song Dynasty. Redundant officials and redundant staff also had many adverse effects on the social cost. Compared with previous dynasties, Tang Ming's ritual sacrifice function is weakened, while its secular function is prominent.
