Why can the Han nationality become the largest family in the world today?

If the population of Han nationality is counted from Xia nationality, it is about 2 million, and it has reached about 20 million in Xia, Shang and Zhou dynasties. When the Han Dynasty was formed, the population of the Han nationality had reached more than 50 million, between 80 million and 90 million in the early Tang Dynasty, and reached 1044 1 in the Daguan period of the Northern Song Dynasty.

After the Yuan Dynasty, under the general trend of China's reunification, the snowball of the Han population grew bigger and bigger. In the twenty-eight years of Wanli in the Ming Dynasty (160 1), the population reached1.50 billion (translated by He Bingdi and Ge: Population Studies in China +0368- 1953), p. 262). In the thirty years since the Qing Daoguang reign (185 1), it has reached more than 400 million. When People's Republic of China (PRC) was founded, its population was about 600 million, and by the end of the 20th century it had reached 1 100 million. Geographically, it has developed from the Yellow River and Yangtze River basins to the Pearl River basin, to Taiwan Province Island and Hainan Island, and to the northeast.
