Is Kang En Pharmaceutical Co., Ltd. related to Sunny Hall?

It's okay. Yanyangtang is the brand of Shenzhen Yanyangtang Pharmaceutical Co., Ltd., while Kang En Pharmaceutical Co., Ltd. mainly deals in the sales of health care products, first-class medical devices and economic information consulting services, so Kang En Pharmaceutical Co., Ltd. has nothing to do with Yanyangtang. Shenzhen Yanyangtang Pharmaceutical Co., Ltd. is the sales company of Hong Kong Weiyuantang Pharmaceutical Co., Ltd. in the domestic market. In the 23rd year of Guangxu reign in Qing Dynasty (1897), it was founded by several partners who came from an official family. Traditional pharmaceutical secrets have been handed down from generation to generation.
