Not difficult. As long as you are majoring in acupuncture and massage, you will meet for one month. If you have 5- 10 years of clinical experience in acupuncture, you can't get through it at all, and the rest is just proficiency. As for the effect, it is useless to look at personal skills. It is fundamental to practice mountain fire and cool the weather, and qigong is better. At present, one or three needles are mainly used to assist strange points, and even needles are not needed.
