Filling Huguang in Jiangxi was a large-scale immigration activity at the end of Yuan Dynasty and the beginning of Ming Dynasty. A large number of Jiangxi people moved to Huguang (now Hunan and Hubei provinces), which had a far-reaching impact. It is said that after Zhu Yuanzhang became emperor, all his factions went to Nanjing to celebrate his birthday. Tired of coping, he ordered everyone to go to Beijing in turn. As soon as I heard that a group of people had arrived in Changsha, I ordered "three days' rest", only to be misinformed as "three days of blood washing". After the Changsha massacre, it was sparsely populated. Many years later, a pair of young men and women from Jiangxi came to Changsha to live and work in peace and contentment, and their children and grandchildren multiplied. Changsha people therefore call Jiangxi people "cousins" and regard Jiangxi as their relatives. Born in the late Yuan Dynasty and early Ming Dynasty, it was a large-scale immigration activity. A large number of Jiangxi people moved to Huguang (now Hunan and Hubei provinces), which had a far-reaching impact. In the history of our country, there have been waves of immigrants again and again. This can get some information from folk proverbs such as "going west", "going east" and "banishing Yunnan" handed down from immigration activities in that year. In Hunan and Hubei provinces, there is a folk saying that "Jiangxi fills the lake and is wide." Huguang "is the name of the ancient provincial administrative region." The Yuan Dynasty included Hunan, Guangxi, Hainan and parts of Guangdong, Hubei and Guizhou. In the Ming dynasty, it was changed to basically govern today's Hunan and Hubei provinces. After the Qing Dynasty divided Huguang into Hunan and Hubei provinces, the name "Huguang" was still used. The governors of the two provinces were called Huguang Governors, but they were no longer the names of the first-level administrative regions. Huguang, as mentioned in folk proverbs, refers to the jurisdiction in Ming and Qing Dynasties. This folk proverb is accompanied by many vivid legends. For example, many people in Hunan and Hubei (especially in rural areas) call themselves "Jiangxi species", saying that every descendant of Jiangxi people has an extra nail on his little finger. For example, in some places in the two lakes, going to the toilet is called "relieving yourself". The locals explained that because their ancestors were bound and escorted to the ship, when it was convenient on the way, they had to ask the escort officers and soldiers to untie the ropes in their hands, so "relieving oneself" became synonymous with going to the toilet and has been passed down to this day.
