参考译文：

Acupuncture is an important part of traditional Chinese medicine (TCM). In accordance with the "main and collateral channels" theory in TCM, the purpose of acupuncture is to dredge the channel and regulate qi and blood, so as to keep the body’s yin and yang balanced and achieve reconciliation between the internal organs. It features in traditional Chinese medicine that “internal diseases are to be treated with external therapy”. The main therapy of acupuncture involves using needles to pierce certain acupoints of the patient’s body, or adopting moxibustion to stimulate the patient’s acupoints so as to stimulate the channels and relieve pain. With its unique advantages, acupuncture has been handed down generation after generation and has now spread all over the world. Nowadays, acupuncture, along with Chinese food, kung fu (otherwise known as Chinese martial arts), and traditional Chinese medicine, has been internationally hailed as one of the “four new national treasures.”
