Chang's family, originally from Dengfeng, came to Zhengzhou a few years ago and started a stationary shop in the city. Yuexia's mother said her daughter was an introvert and met her "boyfriend" on Internet. "She brought him home once, but I was not satisfied with him. Since my daughter liked him, I didn't say anything". "If she comes back, I will communicate more with her and make up for our mistakes", the mother said. [Photo/CFP]
