Tung Chee-hwa told last night how he never knew how much his father loved him until after his death. Speaking during a television interview intended to show his 'softer side', Mr Tung said of his father, Tung Chao-yung: 'He rarely expressed his emotions, although all along I guessed he cared about me. 'After he passed away, I read his diary in which he frequently mentioned me. It dawned on me then how much he really cared about me.' In the ATV programme, When Ken Chan Meets Tung Chee-hwa, Mr Tung chatted with quiz show host Ken Chan Kai-tai about his personal life as the pair strolled around the garden of Mr Tung's Fanling residence. Filmed as part of Mr Tung's campaign to boost his public image ahead of his inevitable re-election as chief executive, a smiling and relaxed Mr Tung also told how he courted his wife, Betty Tung Chiu Hung-ping. He said they fell in love in England where they were both studying in the 1950s. They dated for six years before marrying in the United States. Mr Tung said that when he was younger, he travelled all over the world with his father on business trips, during which he learned the meaning of failure. 'First, it's greed. Many people are greedy. Second, it's the inability to use the right person. Third, it's the inability to do the right thing at the right time. Sometimes things are not within your control.' Mr Tung also revealed that in spite of his 'seven-eleven reputation' - he is widely believed to wake at 7am and work until 11pm - he actually gets up at 4am every day. 'I can get by on six hours' sleep. And why get up so early? Because when it's quiet, I can drink some [tea], clear my mind and read documents. At 6.30am, I do tai-chi, take a bath and then have my breakfast,' he said. He said his early hours were unfair on Mrs Tung, but 'she knows my working needs'. Chan, host of Who Wants To Be a Millionaire, said Mr Tung was 'very honest and didn't sound bureaucratic at all'. The second and final part of the documentary screens tonight.
