Can Tanzhou Drugstore Use Zhuhai Social Security Card?

You can't. Tanzhou is the southernmost town in Zhongshan. Tanzhou belongs to Zhongshan, but because it is close to Zhuhai, many aspects of life here are influenced by Zhuhai. You can't buy medicine in Zhongshan with Zhuhai social security card. Medical exchanges between Zhuhai and Zhongshan are limited to hospitals. Zhuhai Social Security Card can be used in Zhongshan Hospital, and Zhuhai and Zhongshan can make online cloud settlement through the medical insurance platform. If Zhuhai medical insurance card goes to Zhongshan's ordinary pharmacy to buy medicine, it is still not available at present.
