In fact, Jiajiang ceramic enterprises are very good.
But there are also some small factories that have no strength at all. I recommend some factories.
For example, Xinzhongyuan (Xinchang Town) belongs to Xinzhongyuan Enterprise in Foshan, Guangdong. And Miranno (Loess Town, hehe. . . My classmate's father opened it) and Jianhui Ceramics, a local private enterprise, are also good. (Tumen Township) and HKUST (loess is also very good), but the threshold of these enterprises is a bit high.
I hope you can think about it.
