Mainly immigrants from the Ming Dynasty: Immigrants from Yunnan Fucheng flowed into "Little Nanjing" in the early Ming Dynasty. After Kunming was pacified in the early Ming Dynasty, Zhu Yuanzhang established the Yunnan Chief Envoy Office in accordance with the administrative system of the mainland, and the office was located in Kunming. In the Ming Dynasty, Zhongzhong was also located in Kunming.

Qinglu was changed to Yunnan Prefecture, and the government was located in Kunming City, also known as Yunnan Fucheng. In order to stabilize its rule in Yunnan, the Ming Dynasty implemented the largest immigration in Yunnan's history. The earliest immigrants were 300,000 people who conquered Yunnan.

Later, most of these soldiers stayed in Yunnan and participated in the settlement. After Yunnan was pacified, Mu Ying returned to the DPRK and brought back 2.5 million immigrants. Later, Mu Ying's son Mu Chun moved 300,000 Nanjing people, plus the people who were recruited at that time.

The number of soldiers and civilians who defended Yunnan was no less than 500,000. If we deduct the moisture from these figures, subtract the number of people who died on the way to Yunnan, and add the number of people who were exiled to Yunnan, some scholars estimate that the number of Han people who immigrated to Yunnan in the early Ming Dynasty was estimated.

It was about 1.2 million, while the total population of Yunnan at that time was only more than 2 million. Until the end of the Yuan Dynasty, Yunnan was still a border province dominated by ethnic minorities. This situation only changed after Zhu Yuanzhang's large-scale immigration in the early Ming Dynasty.

Kunming is called Yunnan Fucheng, which is the political, economic, military and cultural center of the province. Mu Ying's family has been guarding it for generations. Fucheng and its vicinity are the focus of Mu Ying's garrison when they come to Yunnan, and Mu Ying takes care of them.

Therefore, for hundreds of years, the Han people in Kunming and even some ethnic minorities said that their ancestors were from Liushuwan, Nanjing. Because there were so many Nanjing people in Kunming, it was called "Little Nanjing" until the end of the Qing Dynasty.

, people can also find many Nanjing market customs in Kunming.
