Nowadays, when we mention the emperor, we generally do not call their names directly, but call their temple names and nicknames, such as the Sui Emperor and the Emperor Wu of Han, these are all titles, posthumously sealed by their descendants, but after the Tang Dynasty, in order to be able to boast the merits of the ancestors, basically how good the title sounds, the name is faint and incompetent, the Sui Emperor, although brutal, but definitely not a straw bag, but the Tang Rulers still gave him this name, so the title gradually lost its role, So people moved the temple number to the front desk. Taizu, Gaozu, Taizong, Gaozong, and so on.
The temple number has replaced the name of the temple, and in the past dynasties, the temple number of "Sheng" has only been used by two orthodox emperors in ancient China, one is the Qing Shengzu Kangxi, here he is not introduced much, because the temple number of the Qing Dynasty is also chaotic, "Zu" can only describe the founding or Zhongxing monarch who has made significant contributions, although Kangxi has this qualification, but his father Shunzhi is the ancestor of the Qing Dynasty, the father and son are all ancestors, and the generations are not chaotic? This may be related to the fact that the Manchu rulers did not understand the Central Plains culture. Therefore, historians now call the emperors of the Qing Dynasty by the era names (Kangxi, Yongzheng, Qianlong).
And the only one who used the temple name of "Shengzong" was the sixth emperor of the Liao Dynasty, Liao Shengzong Yelü Longxu, what merit did he have? The Liao Dynasty is arguably one of the most successful dynasties in history, actively learning the Tang system and building a huge empire. In 971, Yelü Longxu was born and was made crown prince, and when he was 11 years old, his father Liao Jingzong died, and the famous Empress Xiao of the Liao state acted as the ruler, because the emperor was young and the imperial court was in turmoil, and Yelü Longxu's position of imperial power was greatly challenged. Fortunately, Empress Xiao was a strong woman, and she had no iron fist to suppress those forces that opposed her.
In 986, the Song army was divided into three ways under the orders of Song Taizong, and from the perspective of a Central Plains person, it was natural to recover the lost Yanyun Sixteen Prefectures, but from the perspective of the Liao State, this move had a little meaning of bullying orphans and widows.
Liao Shengzong was already able to grasp some of the power, he pacified the soldiers, rewarded the meritorious generals, and finally successfully repelled the Song Dynasty troops, after which, Liao Shengzong actively reformed internally, vigorously rectified the administration of officials, appointed ancestors, opened up science and technology, and strengthened the role of the Han in the ruling clique, which brought strong vitality to the entire Liao state.
Throughout history, the regimes established by the nomadic peoples after the unification of the state were often not long-lasting, and the fundamental reason was that they were not very able to manage and improve their own models, but Liao Shengzong did this, he launched a military conquest of the Song Dynasty, united with the Xiang clan, and at the same time used troops against the Korean Peninsula to expand his territory.
Yelü Longxu also grasped the bottom line, and the Song army established an alliance with Tanyuan, which was a relatively good thing for both sides, and for the next hundred years, the Liao and Song dynasties never fought, and the Liao state was able to continue for two hundred years, which was very rare in the era of the collapse of the regime, and the "History of Liao" also commented that he was "a very wise monarch who "reasoned for grievances and stagnated, acted in a way, detected greed and cruelty, suppressed extravagance, recorded the descendants of death, revived the poverty of the various tribes, and was responsible for pandering to the crime of disloyalty". For this reason, it is not unreasonable for Yerushalayim to be called a holy sect.
