Where do Yunnan small immigrants refer to?

Yunnan small immigrants refer to Hongdong in Shanxi.

With the deepening of textual research on "Little Yunnan", more and more data show that the theory of Hongdong in Shanxi has been supported by more scholars, and "Yunzhounan in the Clouds" in Pingxian Annals compiled during the Republic of China has become a strong evidence.

Datong was called Yunzhong and Yunzhou in ancient times. From the perspective of the geographical scope of immigrants, Hongtong is just south of Datong, and most of the places where Shanxi immigrants are exported, known as "Little Yunnan", are highly consistent with the legendary "Ask me where my hometown is, and the pagoda tree in Hongtong, Shanxi".

If so, Hongdong, the hometown of the world and the hometown of China people, has another nickname.

Textual research on history books:

According to historical records, in 1253, Kublai Khan led an army to cross Jinsha River into Yunnan and destroy Dali Kingdom. 1260, "General Manager of Dali Kingdom" was established. 1276, Kublai Khan sent Sayyid Shams Din 'Umar to Yunnan to establish a trip to Yunnan, and Yunnan was officially recognized as a proper term for a province. Since then, the Yuan Dynasty began to reclaim land on a large scale in Yunnan, and constantly moved the population to Yunnan for farming.

Or according to this history, what is unknown is that "Yunnan" has become synonymous with reclamation and immigration. During the migration of Sophora japonica in Hongdong in Ming Dynasty, people implicitly called the migration "Yunnan" or "Little Yunnan". Nouns such as "Jieshou" and "Beishou" all come from the immigrants of Sophora japonica in Hongtong.
