A 21-year-old man and his 19-year-old girlfriend sold their illegitimate son for 2,500 yuan ($366) and bought a flashy mobile phone with that amount in Chongqing municipality.
The one-month-old infant was last week rescued from a trafficker who was about to sell off the baby for 10,000 yuan.
Li, the father, a migrant worker, said his girlfriend Xin gave birth recently, but they didn't have money to take care of the baby, which is why they decided to sell him off.
"When I got 2,500 yuan for the baby, I thought I might as well buy the phone I always wanted," Li said.
Li and Xin have been detained.
