President Jiang Zemin, the Chief Executive's aide Andrew Lo Cheung-on and Hong Kong University vice-chancellor Professor Cheng Yiu-chung feature in a campaign song for the Democrats and Confederation of Trade Unions. The names of Mr Lo and Professor Cheng, two key figures in the controversy over Robert Chung Ting-yiu's opinion polls, have been adapted into satirical lyrics sung by Democrats James To Kun-sun, Wong Chung-ki and unionist Lau Chin-shek. The contenders, on a joint ticket in Kowloon West, said they would feature more headline news and other issues in the campaign song. Mr To said they thought it was a good way to arouse awareness from the public, and they would change the lyrics at different stages of the campaign. The trio also made fun of a recent meeting between President Jiang and SAR tycoons in Beijing, which they termed 'secret talks ' on local affairs and an attempt to boost Tung Chee-hwa's popularity. A Liberal Party candidate in New Territories West followed the example of Taiwan President Chen Shui-bian in handing out copies of a short biography of himself yesterday. David Yeung Fuk-kwong said he had been inspired by Mr Chen whose biography was published when he was elected mayor of Taipei in 1994. Mr Yeung's 20-page biography tells how he grew up in a squatter area and later became a barrister. He prepared 100,000 copies and handed out about 1,000 with his autograph in Tsuen Wan.
