BEIJING (Reuters) - A Chinese businessman has advertised on the Internet for a stand-in mistress to be beaten up by his wife to vent her anger and to protect his real mistress, Chinese media reported on Monday.

"When the woman found out her husband had a mistress, she insisted on beating her up," the Beijing Youth Daily said, citing the advertisement posted on a popular online jobs forum on sina.com.

More than 10 people had applied for the job, the newspaper said. The "successful" candidate would be 35 and originally from northeastern China and would be paid 3,000 yuan ($400) per 10 minutes, it said.

Many Chinese businessmen keep mistresses in second homes, a trend banished after the Communists swept to power in 1949 but which has made a comeback with market reforms in recent decades.
