A couple in Zhaoqing in Guangdong may have to pay more than 10 million yuan in social fostering fees after having eight babies in October 2010, according to Jiangxi Satellite Television.

After trying unsuccessfully to have babies for years, the unnamed couple tried IV treatment. Eight embryos were placed in the uterus of the wife and two surrogate mothers.

The woman herself had triplets in Hong Kong and the other two women had five between them, giving the couple four boys and four girls. China’s one child policy does not apply to twins or triplets, but having the five children by the surrogate mothers is considered a breach of China’s family planning laws, according to Guangdong Planning Commission.

China has banned surrogacy since 2003. As well as conducting a lengthy investigation into the couple’s activities, authorities have also been investigating agencies that offer surrogacy services.

The couple is said to have earning power of over 1 million yuan a year and spent around 1 million yuan on the test tube procedure. It already costs the couple around 100,000 yuan a month to raise the kids.

The size of the fine is calculated according to how much a family earns. Being high earners, this couple could face a 5-10 million yuan fine.
