I just checked on the map of prefectures in Hubei on Wkp*dia, and clicked on the prefecture that’s in the area on the map and looked for the county on the map of the prefecture for the right shape and location
I found this article, which might be a clue. Estradiol starts as a cooking oil by-product. Hubei seems to be a hot spot for cooking oil plants, and I did find a few in that general area, although most of China’s production appears to be located northeast of there. That’s about as far as I got. I’m questioning the veracity of this, but it’s not worth it to me to prove it one way or the other. Details are becoming more difficult to dig up.
