Hello everyone, this video is a more realistic content. It was given to me by a doctor during my recent physical examination. I found that it was the content I usually do when making videos, so I asked the doctor to tell me the specific steps. When I went home, I urgently made this video. I added BGM because my community is really noisy and I don't know if it will affect everyone's experience. If I feel that BGM is a bit noisy or the background is too noisy, I will make another one. I hope you like it and love you
