The Chain family has a long and prestigious history as medical practitioners of Chinese Medicine. The origins of Chain’s Medicare Centre lie in Ban Chuan Tong (as it was then known) or "萬全堂", first founded during the Qing dynasty in the l8th Century by Chain Chi Tai, who was the Imperial Doctor of Emperor Qianlong. Based in the city of Xiamen in Fujian province, Ban Chuan Tong was well-known throughout China and Southeast Asia for its excellence in medical care. The medical traditions of Ban Chuan Tong is carried on through Chain’s Medicare Centre by the descendants of Chain Chi Tai. Chain's Medicare Centre is managed by Dr. David Chain who is a professional doctor in western medicine and Mrs. Kelly Chain, a Registered Chinese Medicine Practitioner.
