Which brand of wheelchair is of better quality? Where can I sell it in Hangzhou?

To the east, opposite Run Run Run Run Shaw Hospital, there is a medical equipment vendor. They have the most wheelchairs, including Otto Bok in Germany, Sangui and Jinri in Japan, Hubang in Shanghai, Tai Fang and Yang Kang in Taiwan Province. I bought a Yang Kang wheelchair from there, which is quite good, but I heard that the German Otto Bock wheelchair is the best, commonly known as the "Mercedes-Benz" in wheelchairs, which is used by my old people. One is to ensure the quality of things after sale, and the other is that their service is particularly good and they can be delivered to your door when it is inconvenient. I have their contact information here, you can call for advice: 86⑦ ⑦ ⑦ ⑦ ⑦ ⑦ ⑦ ⑦ ⑦ ⑦ ⑦.
