According to the Law of People's Republic of China (PRC) on the Protection of Consumers' Rights and Interests, consumers have the right to know, choose, participate, supervise and be protected according to law when purchasing goods or receiving services. If the service purchased by consumers fails to achieve the expected effect, they may request a refund or re-provide the service.

For medical services, the state also has relevant policies and regulations. The Regulations on Handling Medical Accidents in People's Republic of China (PRC) stipulates that medical institutions should ensure that medical technology conforms to scientific norms and medical quality conforms to medical and health industry standards and norms when providing medical services. If the medical institution fails to ensure the quality of medical treatment, resulting in poor treatment effect, consumers have the right to demand a refund or compensation.

Therefore, if the treatment effect of Qingzitang in Xiangtan is not good, consumers can ask for a refund. Consumers are advised to communicate and negotiate with medical institutions first. If they can't solve the problem, they can complain to the local government or seek legal aid.

At the same time, consumers should pay attention to verify the qualification and reputation of medical institutions when choosing medical institutions, and avoid choosing bad medical institutions or branches of bad medical institutions.
