Dear chaircheese,
These village or place names such as "Sanjiaodi" in Pudong has been abandoned now (You can see this page: http://www.stats.gov.cn/sj/tjbz/tjyqhdmhcxhfdm/2022/31/01/15/310115009.html
The "Sanjiaodi" isn't listed there). You can try to remove them and put the names in OHM or just marked as a locality. I hope you can review that whether these names are vaild or not, thanks.
