Xiangtian Wing Wall Glaze was registered in Shandong, and it was produced in a factory in Shanghai. I checked a lot of information. The owner of Xiangtian Wing Wall Glaze was

from Shandong, and the earliest time to develop Xiangtian Wing products was in Shandong. Therefore, the companies and trademarks registered in Shandong were actually produced in Shanghai. After all, Shanghai is much richer in raw materials than Shandong, which can save a lot of

transportation costs.
