A WOMAN who says she is the illegitimate daughter of Zhou Enlai is in fact the daughter of an accountant who has changed her name many times and invented details of her life, the Chinese Government said, dismissing the claim. Ai Bei, who claimed to be the illegitimate daughter of the late premier in her book, He's Too Heavy - He's My Father, was born to a farming family in Yuanji village, in Wuhe county of Anhui on December 28, 1955, said Xinhua (the New China News Agency). Xinhua also criticised the book's presentation, saying it was misleading because it carried photographs of Zhou and Ai and had phrases like ''the life mystery of Zhou Enlai's illegitimate daughter'' on its cover, despite being a novel. Certificates with photographs matching those in the book, and the woman's relatives, could prove the identity of Ai, originally called Zhang Aipei, said Xinhua. Xinhua said the woman's real father, Zhang Zhaofang, became an accountant in an agricultural co-operative in the 1950s. He died of an illness in 1960. Xinhua also denied that her mother, Huang Julan, now over 80, has anything to do with ''An-ran'' described in the book. According to Xinhua, Zhang, who has changed her name several times, went to primary and secondary schools in her home town and to Bengbu Medical College, where she used Ai Pei as a pen name. She served as a doctor in a hospital attached to the college. She married in 1984 and, was transferred to Beijing to join her husband, where she changed her name to Zhang Aibei. In 1986, her husband went to study in the United States, where she visited him two years later and stayed on. She made a trip to her home town in 1992 to see her mother and has kept in contact with her family. The woman had invented her education and work experience on several occasions, such as when claiming her birthplace to be Beijing while applying to go to the US, Xinhua said.
