Li is the most popular surname in China, and many people claim to be descendants of the royal family, that is, Li in Longxi. In fact, before the Tang Dynasty, Li was the most popular name in China, among which Zhao was the most famous. After its establishment, Li became a national surname and became more prosperous. For a long time, Li was the most popular name in China, and many people claimed to be descendants of the royal family. In fact, there is no descendant of Li Tang royal family in modern Li family. When the Li Tang dynasty was strong, there were few members of the royal family in Li Tang. By the time Wu Zetian came to power, there were only more than 200 members of the royal family in Li Tang. Although most of these people had no real power, they fought against the usurpation of power by Wu Zhou to the death and were killed by Wu Zetian. Only a few people survived. During Xuanzong period, the royal family of Li Tang ushered in a period of stable development. However, decades later, the Anshi Rebellion broke out. In retaliation for the murder of Emperor Xuanzong of the Tang Dynasty, the Anshi Rebellion killed Li Tang's royal descendants. The main battlefield of the Anshi Rebellion was in the north, which was the main fief and residence of the royal descendants. The royal family in Li Tang suffered extremely heavy losses. After the Anshi Rebellion, the Tang Dynasty was no longer strong, with eunuch authoritarian power inside and vassal separatist regime outside, and the political situation was turbulent. Every time the royal family was in turmoil, it was hard to escape, and the children of the royal family were killed repeatedly. At the end of the Tang Dynasty, the royal family in Li Tang suffered an unprecedented Huang Chao Rebellion. If the Anshi Rebellion was confined to the north, then the Huang Chao Rebellion swept across the north and south, and the royal family of Li Tang became the main target of Huang Chao's cleansing. After Huang Chao's defeat, the warlord in the buffer region killed the royal family in Li Tang. Finally, Zhu Wen completely buried the royal family in Li Tang. In the history of China, the Tang Dynasty not only created a prosperous time, but also created two miracles: First, the royal family suffered from constant disasters, and the imperial dynasties that lasted for hundreds of years were all killed at the end of national subjugation, unlike the royal family in Li Tang, which started with the change of Xuanwu Gate, the Tang Dynasty in Wu and Zhou Dynasties, the Anshi Rebellion, the separatist regime in the buffer region, the Huang Chao Rebellion and the Tang Dynasty compiled by Zhu Wen. The second is to turn Li's surname into the most popular surname in China. Before, Li was the most popular surname. In Li Tang for more than 200 years, he kept giving surnames to Hu people and Han people. The tribes of the Hu people often follow the tribe leader's surname Li, and Li becomes the first surname. These people claimed to be descendants of the royal family of Li Tang, but the real royal family of Li Tang disappeared without a trace. In recent years, archaeological excavations have uncovered the tombs of many members of the royal family, such as princes, princesses and kings in Li Tang. According to modern genetic technology, genetic testing has been carried out, focusing on those who have credible genealogy and credible relics, especially Li Gaihu, who is recognized by everyone. Through genetic testing technology, it has been proved that none of these people are related to the royal family of Li Tang. The current test results prove that the royal family in Li Tang has indeed become extinct, which is completely consistent with the official records. Today, there are hundreds of millions of people surnamed Li, but none of them are descendants, which is embarrassing.
