It is said that when xihua university asked the Chengdu municipal government to delimit jinniu district, he set up his household registration at No.999, Jinzhou Road, Tuqiao, jinniu district, Chengdu. But later, the campus expanded and occupied part of Pixian land, so part of it also belonged to Hong Guang Town of Pixian County. Some paper maps clearly indicate that some of them belong to jinniu district. So now we live in Pixian County, have classes in jinniu district, and shop in Hong Guang Town of Pixian County, which is very interesting.
