Acupuncture can be done in the evening, but Chinese medicine is concerned with the idea that heaven and man correspond to each other, usually in the morning when yang energy is more abundant, the effect of acupuncture will be better. The effect of acupuncture at night is not as effective as when the yang energy enters the yin energy and the yin energy is strong. Nowadays, people are too busy to do acupuncture at night because they are not able to do it during working hours. However, it is believed that the effect of acupuncture in the morning will be better, and the effect of acupuncture in the evening will be worse. Just like the commonly said acupuncture and moxibustion, doing moxibustion at night will be done for a long time and is not very suitable. So it is better to go for acupuncture in the morning to achieve twice the result with half the effort.
