Shenzhen Party Secretary Huang Liman spoke out against corruption yesterday, indirectly criticising the city's propaganda chief for allowing his wife and daughter to become involved in the entertainment industry. Ms Huang, speaking on a nationwide teleconference on corruption, vowed Shenzhen would continue to crack down on bribery. She warned officials not to accept gifts during New Year celebrations. The party secretary said she would sack officials caught taking bribes or involved in gambling. In an apparent reference to controversy surrounding the city's propaganda chief, Ms Huang said: 'Cadres must not allow their wives or children to conduct business activities within the sector overseen by themselves.' Earlier, Shenzhen Deputy Party Secretary Li Yizhen was publicly chided after five local authorities were found to have forced students to watch a film that his daughter wrote, produced and starred in. Mr Li is in charge of the city's propaganda, media, cultural and entertainment industries. His wife and daughter were later found to have owned companies selling educational and entertainment products. The incident triggered widespread criticism from media outside Shenzhen and from the public. Mr Li apologised publicly to the students and their parents. The Shenzhen Party Committee later concluded that he had not asked for special treatment for the movie, but said the propaganda chief had lacked sensitivity in handling the issue.
