Do you think that the immigrants of Sophora japonica in Ming Dynasty played an important role in the cultural history of China? Why?

The reconstruction of Shandong villages caused by the great migration of population in Ming Dynasty is of great significance. First of all, it has promoted the increase of population. Twenty-eight years after Hongwu, Zhu Rong, commander-in-chief of the army, said that Dongchang, Daming and Guangping had 58 124 immigrants. The proportion of Dongchang is not clear. On average, there are 19375 households in Dongchangfu. Judging from the distribution of Hongdong immigrant villages in Heze area, Hongdong immigrants in Heze area are not less than Dongchangfu. According to the calculation of Dongchang Prefecture 19375 households, there are about 38,750 immigrants from Dongchang and Yanzhou Hongdong, with each household 193750. The number of immigrants from Heze Zaoqiang is difficult to test today. Judging from the distribution of Zaoqiang immigrant villages, it is less than Dongchang and Yanzhou. The number of Yunnan immigrants and Sichuan immigrants is unknown, but the scale is definitely smaller than that of Hongdong immigrants. In addition, immigrants from other areas entered Shandong in the Ming Dynasty, such as Henan, Anhui and Jiangsu, especially from Haizhou, Rizhao and Jiaonan. If the immigrants from Zaoqiang, Yunnan, Sichuan and other provinces are counted as 19375 households in Dongchangfu, the total number of immigrants from other provinces in Shandong in the Ming Dynasty is about 58 125 households with 290625 people. Second, it has promoted economic development. The immigrants entering Shandong are mainly cultivated land, which has played an important role in promoting the development of Shandong agriculture. In this regard, Ming Taizu Shi Lu has a clear record. For example, in December of the 25th year of Hongwu, Li Ke and Li Li, the commander-in-chief of Houjun, reported that there were 598 immigrants from Zhangde, Weihui, Guangping, Daming, Dongchang, Kaifeng and Huaiqing. "This year, we collected more than three million stone millet and wheat,18.03 million kilograms of cotton and 2180,000 hectares of wheat seedlings. He was very happy and said,' Ten years later, there are few poor people in our people.' "("A Record of Ming Taizu "Volume 223) In November of the 28th year of Hongwu," the commander-in-chief of the army, Zhu and Dongchang, moved 58,124 households, rented 3,225,980 yuan of grain and spent 2,480,000 Jin of cotton. "Third, it promoted the rectification of folk customs. People are the "comprehensive carrier" of folk customs. When a person or several people enter a new folk circle, they are often assimilated by local folk customs, which is called "when in Rome, do as the Romans do". However, when a large group of men and women keep crowding in, it is difficult to eat all the local folk customs at once. Immigrants from other provinces entering Shandong are generally relatively concentrated in a certain area. For example, Hong Tong immigrants are mainly distributed in Dongchangfu and western Yanzhou, Zaoqiang immigrants are mainly distributed in Jinan and northern Qingzhou, Yunnan immigrants are mainly distributed in Laizhou and southern Dengzhou, and Sichuan immigrants are mainly distributed in Ye County, Laizhou. In these areas where immigrants are mainly distributed, the folk customs of local aborigines cannot be completely assimilated, and the folk customs of immigrants and local aborigines are reorganized in the process of integration to form new folk customs. The folk customs in Laizhou are obviously different from those in the surrounding areas, because Laizhou was the center of Sichuan immigrants in the Ming Dynasty. Another example is that Jimo is a relatively concentrated area of Yunnan immigrant villages, and the folk customs around Jimo bear the brand of Yunnan immigrants. The "Bangzi Opera" popular in Liaocheng and Heze, Shandong Province, also known as "Zezhou Tune", was brought to Shandong by Hongdong immigrants.
