In 2006, famous singer Liu Huan served as an "Anti-Drugs Ambassador" for the first time. He said that he was influenced by Pu Cunxin, a famous actor in China. "We are neighbors, and he influenced me a lot as he has been working on campaigning for HIV prevention and blood donation," Liu said. He said that rather than producing masterpieces under the influence of drugs, many talented musicians and artists have destroyed their careers because of drugs.
