What about the fennel health APP developed by Shi Jianqiang Kang? Is it useful?

I know fennel health, which is the earliest consultation APP I downloaded. I often go to the door for consultation and have experienced it many times. I communicate with real doctors there, and all departments have experts to sit and consult, so it is easier to register. The most important thing is that the doctor is really experienced and has a very good attitude. In many ways, it is suitable for people who are inconvenient to go out, such as the elderly.
