Why did Sun Yat-sen go to the Ming Tombs to worship Zhu Yuanzhang?

When Sun Yat-sen went to the Ming Tombs to pay homage to Zhu Yuanzhang, he was the president of the Republic of China. Moreover, from the end of the Qing Dynasty, the whole country was tottering and the people were in dire straits, which was precisely caused by the Qing Dynasty. After the defeat, Sun Yat-sen expelled the Tatars and restored China. Naturally, he told Ming Taizu that I inherited your legacy and restored the Han family. From here, we can also see some nationalist tendencies of the Han nationality. At that time, the harmony of the five ethnic groups was also dominated by the Han nationality.
