I tell you, diagonally opposite the Shi Hao Hotel, there is a Baekje Tang pharmacy, which is sold there. There is also a place, in the north of the county hospital, where there is a large frontage room, where medical devices are put and sold. Let me make it clear to you first, it is very expensive to buy a wheelchair in Miyun, 400~600 yuan, so so-so.

Finally, I wish your grandmother good health!
