WHEN Mr Chen's wife appears with him, she is a living witness to the political violence and corruption he has promised to end. Wu Shu-jen was crippled in an horrific attack on November 16, 1985, when she was run over three times by a truck in Tainan, her husband's home town in southern Taiwan, shattering her spine into 30 pieces. Despite two major operations and six months in hospital, she lost the use of the lower half of her body and will be confined to a wheelchair for the rest of her life. Many believe that the attack was carried out by agents of the Kuomintang or gangsters paid by them. Ms Wu was born in 1953 into a well-off family in Taipei, her father a physician. A lively and vivacious girl, she studied at a private girls' school and graduated from Chung-Hsing University in Taipei. She and Mr Chen married on February 20, 1975, despite the opposition of her father who felt that Mr Chen was too poor and from too low a social background. They have two children - a daughter who is a dentist and a son who, following his father, is studying law.
