Which dynasties in China had emperors of foreign descent?

In the Eastern Jin Dynasty, the vast majority of the sixteen northern countries were pure-blooded conference semifinals, and in the Southern and Northern Dynasties, the Northern Dynasties were also conference semifinals. Since the Sui Dynasty, the so-called Han nationality is actually the new Han nationality after the great ethnic integration, and there is no royal family of pure Han nationality. In other words, even if there is, after several major national integrations, its lineage has been impossible to verify. Since the Sui Dynasty, the genealogy of the royal family has been fabricated by whitewashing, and the genealogy cannot be verified. Emperor Wendi said that he came from Hongnong Yang and actually had Xianbei descent. Li Yuan said that he was a native of Longxi, but he was actually a Turkic descendant. After the Five Dynasties and Ten Kingdoms, the lineage became more chaotic. Zhao Kuangyin is said to be of Shatuo descent, not to mention Zhu Yuanzhang's ancestors. In the Southern Song Dynasty, he was ridiculed by later scholars for 500 years. Therefore, Sima Shi is a sinner through the ages, and the Han lineage has not been seen since the Jin Dynasty.
