Created by Hongxhi Xiao, Paida ( Slap-Therapy) is a current trend in Asia particularly common in China and Taiwan. Inspired by Taoist and Buddhist ideas, Paida's goal is to deplete sha, or "poisoned blood", from the patient's body. This method presents an interesting methodology, a growing acceptance, and an opposition.

Paida involves bruising certain parts of the body, as the bruise is viewed as the sha appearing; therefore, the more bruises, the better. There are even instances of covering a patient's entire body with bruises, which is considered healthy and beneficial. Believers of this method may also incorporate certain mixtures of herbs into the process by soaking their hands. Xiao advertised this method by claiming Paida can cure and ease symptoms of diseases like colds, diabetes, cancer, and Alzheimer's. Xiao also stated his method can cure paralysis, strokes, and pains. He even went as far as to say it can cure disorders like Autism. Xiao's claims did not, however, convince Taiwan's government. Xiao was fined by Taiwan's government for fraud in 2011. Despite this, citizens still continue to use the process and claim Paida is effective in curing their ailments.

Paida's growth can be witnessed through its international workshops. For instance, these workshops exist in Australia and in the U.K. Unfortunately, Paida has been fatal for some. The parents of Aidan Fenton, a 6-year-old boy suffering from diabetes, decided to have him treated with Paida in an attempt to cure the disease. However, the intense, abusive activity led to the little boy's death, and the parents were charged. A similar situation occurred in a workshop in the United Kingdom, where three followers were charged with manslaughter. Despite the fatal results, the practice and its followers continue to grow.

In fact, the population that uses Paida has grown so immensely many companies consider it profitable to produce equipment for the purpose of Paida, including specially designed "slappers", or rubber hands advertising a better and more effective Paida experience. Industries have also developed tutorials on how to perform Paida correctly, such as videos demonstrating how to hit the head correctly and books about where to hit in order to cure a disease.

Despite government denunciation and a lack of research to support the practice, claims of Paida's efficacy and success continue to persist.
