Xi 'an, where can I rent a medical oxygen bottle?

There is a Pusen pharmacy 200 meters west of Xishaomen Cross, where you can buy and rent medical oxygen bottles of various sizes. I've been driving all day and his door says medical oxygen. It's still very formal, with complete licenses. Call 1 14 to contact Posen Medical Oxygen. The telephone number is 82488336 and the other is 84265528. Many oxygen distribution companies have no oxygen business license and no supervision, and they all take industrial oxygen.
