Introduction: Acupuncture therapy is a traditional Chinese medical treatment method that involves inserting fine needles into specific acupoints on the body to regulate and balance the body's physiological functions. It helps to promote blood circulation, alleviate pain, improve immune system function, and regulate the endocrine system. Acupuncture, as an indispensable part of traditional Chinese medicine, has been spreading worldwide throughout the history of international exchange and dissemination of Chinese medicine. Although the overall trend of "Western learning moving east" mainly involved the importation of "Western learning" into Western countries, it still sparked the first wave of "acupuncture fever" in Europe, which lasted for over 100 years. In the 1970s, a new trend of "Chinese medicine moving west" emerged, starting with the successful announcement of "acupuncture anesthesia" by Xinhua News Agency and the visit of US President Nixon to China. This led to the second wave of "acupuncture fever" in Western countries, particularly the United States, gradually gaining popularity worldwide and continuing to this day. In the context of globalization, acupuncture has been increasingly accepted by healthcare systems in various countries and gradually legalized and standardized. However, the "internationalization path" of acupuncture has not been smooth sailing. This article explores the "main obstacles for Westerners to accept acupuncture therapy" and "whether scientific evidence and clinical efficacy are more convincing to Westerners in accepting acupuncture therapy," in order to contribute to the international dissemination of acupuncture-led traditional Chinese medicine
