Is Amy's integrity the same as that of Shenzhen Kangtai?

It's different. Amy Chengxin Biopharmaceutical Co., Ltd. is a limited liability company, while Shenzhen Kangtai Biological Products Co., Ltd. is a listed joint-stock company, which is different. Shenzhen Kangtai Biological Products Co., Ltd. was established on 1992 and registered in Kangtai Group Building, Kefa Road, Yuehai Street Science and Technology Park, Nanshan District, Shenzhen. The legal representative is Du Weimin.
