How many chain pharmacies are there in Xuzhou?

Hua En He Run Pharmaceutical Co., Ltd. (there are many chains in Xuzhou, the Second Hospital is near the Cultural Palace, and the warehouse direct selling center is on Huaita East Road) Dong Run Pharmaceutical Co., Ltd. (the warehouse direct selling center is near Huaixi Bus Terminal and the food city) Sanjiang Pharmaceutical Co., Ltd. (the warehouse direct selling center is near Chuwangling). I know that these are the three largest pharmaceutical companies in Xuzhou, and almost some small chain stores or hospital clinics in Xuzhou take medicines from these three companies and retail a box of condoms (hehe).
