The 2016 Dating and Marriage Report, released by Shijijiayuan in January, said more than 60 percent of 8,745 single males and half of 7,755 single females on the dating website were being urged by their parents to get married.

According to the more than 16,500 respondents of the report, the average age for "leftover men" was 35 and for "leftover women" 32. Of the respondents, 29 percent of men and 38 percent of women said they would not marry until they found true love.

While well-educated women with good judgment were most favored by men, family-oriented and considerate men were the most favored among women.

"Being money-minded, narrow-minded and causing problems out of nothing" were the top three unacceptable traits in women, male respondents said.

"Being stingy, sissy, quibbling over details and narrow-minded" were the top four characteristics in men disliked most by women.

Men were curious to know if women would be willing to have children and how they felt about living with parents-in-law. Women were keen to know about the economic prospects of their potential partners and their sexual ability. Women were also interested in knowing their thoughts on living with their parents and parents-in-law. Both genders wanted to know about each other's medical history.
