Rivalry put aside for Zen's retirement If there were any strains inherent in the head of the Catholic diocese, Joseph Zen Ze-kiun, having as one of his flock Chief Executive Donald Tsang Yam-kuen - whose policies Cardinal Zen frequently criticised - they were not showing yesterday. As the Vatican made its long-awaited formal announcement of the cardinal's retirement, Mr Tsang was both magnanimous and devout, wishing the pro-democracy prelate 'a very, very happy and holy retirement'. If there was a touch of relief underlying his words, that wasn't showing either. For his part Cardinal Zen enjoyed his favourite breakfast of preserved vegetables with rice noodles in the cathedral canteen after conducting his last Mass as diocese head, then busied himself clearing out his office with 'boxes full of old memories' to be moved to his new residence in the Holy Spirit Seminary in Aberdeen. As parishioners of the cathedral in Caine Road queued to embrace him after Mass, the 77-year-old joked: 'I am not going to heaven yet.' Tsang's honeymoon haven in Taiwan Since the Kuomintang regained its ruling status in Taiwan, the Hong Kong government has been taking every opportunity to publicise the olive branches it has extended to the island. But it was not disclosed until yesterday that Donald Tsang had been a pioneering envoy as early as 1969. After meeting Mr Tsang at Government House, visiting Taichung mayor Jason Hu Chih-chiang revealed this little secret: 'Perhaps not many people know, but Chief Executive Tsang's honeymoon was spent in Taiwan.' The mayor, promoting Taichung's wedding exhibition as the best in Taiwan, was taking the matter seriously. He proposed to Hong Kong Tourism Board chairman James Tien Pei-chun that the two governments should encourage their newlyweds to make honeymoon trips to their respective places, and said he hoped to build 'a bridge of lovers' across the strait. An apology for 'forgetfulness' Remember how former secretary for financial services and the treasury Frederick Ma Si-hang was forced to bow twice in front of television cameras at a press conference he called to apologise for his oversight in the so-called penny-stock debacle in 2002? Yesterday, Democrat Wong Sing-chi was asked to do so, and complied, when he made a public apology for 'forgetting' to renew his registration as a social worker despite having described himself as a social worker while campaigning for election to Legco last year. He is to apply to the courts for an exemption for the breach of election rules, which prohibit inaccurate publicity. Student patrol for those 'killer trees' Legislator Gary Chan Hak-kan is full of ideas to improve the environment - some expensive, some not so. On the one hand he is touting a HK$900 million scheme to install state-of-the-art solar panels at more than a dozen disused landfills, which he says could provide electricity for 3,000 families. 'It is expensive, but it can help save the environment and create jobs,' said Mr Chan, of the Democratic Alliance for the Betterment and Progress of Hong Kong. On the other hand he wants to train teams of New Territories schoolchildren to report trees they see on their way to school that are in danger of falling down and killing someone, as happened in Stanley last year. Any more good ideas, Mr Chan?
