     In a traditional Chinese family, women are expected to do the housekeeping and leave the "other business"

to men. However, the appearance of the full-time "househusband" is changing traditional family.

     A survey in Beijing, Shanghai, Guangzhou and Shenzhen shows that 22 percent, 73 percent, 34 percent and

32 percent of white-collar male workers, aged between 28 and 33, would be prepared to do the housekeeping

if the conditions were right.

     Yang Wenhui, 32 years old, worked at the office of a company prefer to quit (离开) the job. "My job was

dull and steady. I was not promoted (提拔). My wife, in contrast, really likes her job. So, after our baby was

born, I chose to stay at home and take care of the family while my wife works full-time outside the home,"

said Yang.

     Sociologists have found the full-time househusband emerges in three main situations.

     Firstly, if the wife is ambitious (有雄心的), well-paid and has good job prospects, while her husband is paid

poorly and has no job prospects, it makes economic sense for the woman to become the main income earner

for the household. Secondly, if the wife is tired of household chores and eager to work outside the home, her

husband may forfeit his job. Thirdly, if the husband can do his work at home, he may take this choice as it

allows him more time to take care of the family.

     Influenced by traditional ideas, some families with full-time househusbands prefer others not to know about

their arrangement, concerned people would laugh at a husband with "no prospects" or wife who is "too strong". 

     Zhou Wei said he has become usual to being a full-time househusband although his relatives doubted this

when they gathered during the holidays. "A happy life is the most important thing, not other peoples' opinions,"

added Zhou.
