Emperor Ai of Tang
The new Later Liang emperor created Li Chu the Prince of Jiyin and moved him from Luoyang to Cao Prefecture (曹州, in modern Heze, Shandong), and put his mansion under heavy guard, with a fence of thorns surrounding it. In 908, he had Li Chu poisoned to death, and gave Li Chu the posthumous name of "Ai" (哀, "lamentable"). In 928, by which time Li Keyong's adoptive son Li Siyuan was ruling as the emperor of Jin's successor state Later Tang (as Emperor Mingzong), which claimed to be the legitimate continuation of Tang Dynasty and which had earlier destroyed Later Liang, Emperor Mingzong's officials suggested that a temple be built to honor Emperor Ai. Emperor Mingzong had such a temple built at Cao Prefecture. In 929, Emperor Mingzong's officials further suggested giving Emperor Ai a more proper (i.e., more Tang-traditional) posthumous name of Emperor Zhaoxuan Guanglie Xiao, with a temple name of Jingzong, but they also pointed out that since Emperor Ai's temple was not among the imperial ancestral temples, a temple name was not proper. Therefore, only the new posthumous name was adopted, and the temple name was not. Traditional histories thus referred to him mostly as Emperor Ai but also at times as Emperor Zhaoxuan.No family recorded in official histories; Song dynasty general Li Gang was claimed to be a descendant through a son named Li Xizhao (李熙照)
Xianbei
In 534, the Northern Wei split into an Eastern Wei (534-550) and a Western Wei (535-556) after an uprising in the steppes of North China inhabited by Xianbei and other nomadic peoples. The former evolved into the Northern Qi (550-577), and the latter into the Northern Zhou (557-581), while the Southern Dynasties were pushed to the south of the Yangtze River. In 581, the Prime Minister of Northern Zhou, Yang Jian, founded the Sui dynasty (581-618). His son, the future Emperor Yang of Sui, annihilated the Southern Chen (557-589), the last kingdom of the Southern Dynasties, thereby unifying northern and southern China. After the Sui came to an end amidst peasant rebellions and renegade troops, his cousin, Li Yuan, founded the Tang dynasty (618-907); Li led China to develop into one of the most prosperous states in history. Sui and Tang dynasties were founded by Han Chinese generals who also served the Northern Wei dynasty. Through these political establishments, the Xianbei who entered China were largely merged with the Han, examples such as the wife of Emperor Gaozu of Tang, Duchess Dou and Emperor Taizong of Tang's (Li Shimin's) wife, Empress Zhangsun, both have Xianbei ancestries, while those who remained behind in the northern grassland emerged as later powers to rule over China.
