Why is Hengyang dialect so similar to Sichuan dialect?

Take a slow look at the following (Huguang fills Sichuan) and you will know. In Sichuan, people say "go to the toilet" and "relieve yourself". Why? That's because the arrested Sichuanese have to untie their hands when they want to go to the toilet: "Since the Han and Tang Dynasties, there have been many teeth and fireworks in Shu. After the war in the late Ming Dynasty, Dingkou was as rare as the morning star. " According to the population statistics in the twenty-four years of Kangxi, the population of Sichuan Province, which experienced large-scale wars, was only over 90,000 (tens of thousands of people in one town). During the reign of Kangxi in the Qing Dynasty, the Sichuan Basin after the war finally calmed down, and a number of new local officials began to take office. In the eyes of these ambitious officials, I don't know how rich Sichuan is. However, when they rode to the new official residence, they found that the legendary land of abundance was so desolate, broken and riddled with holes.

In the seventh year of Kangxi, Dedi Zhang, the governor of Sichuan Province, played Emperor Kangxi with great anxiety, showing a strong sense of hardship. He said: "I am honored to be appointed as the highest local official in Sichuan by the emperor and come to this war-torn place to show my great ambition. But now, when I stand in the devastated past, I can't increase my income, and it's hard to collect taxes, which makes me feel embarrassed, unable to eat or sleep. I was sent by the emperor, but I am loyal to the country and the court. After a few days of thinking, I feel that there seems to be no other good way to attract immigrants to reclaim land and rebuild their homes. " Historical materials of Ming and Qing dynasties, title book of the Ministry of Housing.

At the same time, Governor Zhang also mentioned some immigration methods in his memorial. For example, local officials in neighboring provinces of Sichuan can be ordered to check those Sichuanese who left their homes because of the war and register them, and then Sichuan can "send officials to take over them" or the government can directly introduce immigration policies and move people from densely populated provinces to Sichuan through administrative means. Emperor Kangxi, sitting on the dragon chair in the Forbidden City, is also struggling with the taxation and reconstruction of the whole country. He received memorials from local officials in Sichuan, called relevant departments to listen to relevant reports, officially issued an imperial edict entitled "Recruiting People to Fill Sichuan in the Thirty-third Year of Kangxi", and ordered large-scale immigration from Hunan, Hubei, Guangdong and Guangxi to Sichuan.
