The praise of the champion began in the Song Dynasty. According to the records in the Hall of Minghui, the champion must be hand-picked by the emperor. After the court examination results come out, they will be sent from the palace and posted on the temporary canopy outside the left gate of Chang 'an. In the Song Dynasty, the ceremony of making flowers for new Jinshi was called "Wen Yanxi", and the emperor personally made flowers for Jinshi. This custom was customized during the reign of Emperor Taizong. Song Dynasty (960- 1279) is the Central Plains dynasty in China history, which is divided into Northern Song Dynasty (960- 1 1279) and Southern Song Dynasty (1 1279). After 960 years, Zhao Kuangyin, the emperor of the Zhou Dynasty, seized the throne through the mutiny in Chen Qiao, established Kaifengfu, the capital of Tokyo, and established the Song Dynasty. In order to avoid the chaos of the regime and eunuch's autocratic power in the late Tang Dynasty, Zhao Kuangyin adopted the policy of worshipping and restraining military power, strengthened centralization and deprived military commanders of military power. Song Taizong succeeded to the throne and ended the separatist regime. 1004, Song and Liao reached a single-source alliance, and Song gradually stepped into governing the world. After Song Renzong, the social crisis in Song Dynasty became more and more serious. After Song Shenzong ascended the throne, Wang Anshi and others were appointed to carry out political reform activities, which achieved certain results, but the Song Dynasty was deeply mired in the struggle between the old and new parties. From 1 125, the rulers invaded the south on a large scale, and in 1 127, Tokyo fell and the Northern Song Dynasty perished.
