Mianzhu immigrant masses

* * Yes, there is indeed a place in Mianzhu County, Sichuan Province called Dahuaishu. You described the situation of Qiujia Laozhuang Village in Lin Hao Township, Xihe County, Gansu Province in great detail. I didn't find a direct connection between the two places. However, because the residents of Qiujia Laozhuang Village are locust tree immigrants, this may be the reason why they chose to name the village Qiujia Laozhuang.
