First Lady Wang Yeping was once mistaken as a nanny by security guards in Shanghai when President Jiang Zemin was the city's Communist Party secretary, an official Web site reported yesterday. Qianlong.com, the Web site of the Beijing Communist Party Committee, said the incident happened in the mid-1980s. China's official media rarely report the details of state leaders' private lives. They are often portrayed as being revered by the public. The embarrassing incident happened one day when Ms Wang visited a friend from Beijing who was staying at an official residence. The report said she was stopped by two security guards at the gate who did not recognise her, and that one of them demanded she fill in a form before being granted entry, as was the standard practice for all visitors. The other security guard was quoted as saying: 'Don't make it hard for her [Ms Wang] - a nanny who can't read. How can you expect her to fill in a form?' However, they realised their mistake when Ms Wang's friend came out of her home to welcome her guest and used the greeting shuji furen, meaning madam secretary. Ms Wang was not annoyed and only smiled as she passed the two security guards, the report said. Ms Wang's public image is a frequent topic of discussion in the mainland media, especially after she accompanied her husband to the United States in a landmark visit in 1997. Her plain and low-key style was often compared to her colourful and classy peers like Zhu Lin, wife of National People's Congress Chairman Li Peng.
