The company has four production addresses, that is to say, there are four branches, the addresses are: No.91Chenglinzhuang Road, Hedong District, Tianjin; No.9 Laoshan Branch Road, Chenglinzhuang Industrial Zone, Dongli District, Tianjin; No.221Huanghai Road, Tianjin Economic and Technological Development Zone; No.91Xinye Jiujie, West Zone, Tianjin Development Zone.
The address you mentioned is only one of its branches, but you can't go directly to the factory to buy it. After all, the factory does not do retail. I suggest you go to the local pharmacy to buy this medicine, just tell the waiter about the manufacturer.
May you buy this medicine as soon as possible and be healthy.
