A poor man has to sign a prenuptial agreement before his rich mother-in-law agrees to let the man and her daughter get married, Wuhan Evening News reported.

The man, 28, is surnamed Zhang and comes from an impoverished region in Bijie, Southwest China's Guizhou province and now works in Wuhan, Hubei province. Three years ago, he felt in love with a girl, surnamed Yang, from Fuyang in East China's Anhui province.

Yang's parents are both civil servants and are financially well-off. Despite the continuous objections of her parents, Yang refused to dump Zhang and insisted on getting married in October this year.

Seeing no hope of breaking up the relationship, Yang’s mother had to give up but required Zhang to sign a written contract, with many stipulations.

Zhang must move to Anhui province to develop his career otherwise he needs to pay 100,000 yuan ($14,900) as compensation. He also must pay one million yuan if he has an extramarital affair.

According to the contract, Zhang must also cook dishes to Yang’s taste and be responsible for washing, cutting and cooking vegetables as well as cleaning dishes.
