In February 2009, it was confirmed that 14 papers published by He Haibo in international journals were plagiarized. At present, He Haibo, the first author of the fake paper, has been dismissed. Zhejiang University said in the statement that "the falsification of papers is mainly the personal behavior of He Haibo, a postdoctoral fellow led by Academician Li, and other authors are unaware of it".

Regarding Li's exemption, Zhu Guoguang said that as a mentor of He Haibo and a co-author of The Theory of Fraud, he could not be unaware of the fact of fraud. Zhu Guoguang hoped that Li would admit his mistake.

As for Li's joint responsibility for He Haibo's forgery, some netizens said that Zhu Guoguang's persistent pursuit of Li's confession was due to economic reasons. Li noted that there are 9 formulations of compound Danshen preparation, which are produced by nearly 800 pharmaceutical companies. The quality is chaotic, and it is difficult to distinguish between good and bad, which is not conducive to rational drug use and improvement of curative effect, and is also not conducive to the majority of patients to choose good drugs with high quality and low price. It is necessary to re-evaluate and study. After a lot of research, it is found that the compound Danshen dripping pills produced by Tasly Group have many shortcomings: low content of active ingredients, poor pharmacological effect, unsatisfactory curative effect, high incidence of adverse reactions, serious nature, long-term heavy use of drugs may cause serious harm to patients, and the drug price is too high, which is 6 times higher than other pharmaceutical products. And in the process of publicity and promotion, they have a lot of cheating and illegal behavior.
