Family members demand that Liu Xue's parents bear the legal responsibility for trafficking and abandonment. How is this legally stipulated?

Liu Xue was betrayed by his biological parents when he was three months old. His adoptive parents died in an accident when he was four years old. He grew up under the care of his grandparents and is currently studying in a technical secondary school. Liu Xue found his biological parents at the end of last year, and the biological parents have established their own families. Because he didn't have a fixed residence, he asked his biological parents if they could buy a house or rent a house for themselves, so his biological parents stopped contacting Liu Xue WeChat.

Relatives of Liu Xue's adoptive parents have reported the case to Datong Public Security Bureau, demanding that Liu Xue's biological parents be held accountable for abducting and abandoning their son, and hoping that they can file a criminal case. Zhou Zhaocheng, the attorney of Liu Xue's adoptive parents' relatives, said that Liu Xue's suicide note can be regarded as his report and report materials, which have been delivered to Datong Public Security Bureau by express delivery.

Liu Xue's family submitted the report materials to Datong Public Security Bureau. According to the report materials, the victim Liu Xue was abducted and abandoned, and asked the Datong Public Security Bureau to conduct a criminal investigation. At the same time, the Datong County Public Security Bureau is required to immediately take criminal compulsory measures against Liu Xue's biological parents and other persons suspected of criminal offences, and investigate their criminal responsibilities according to law.

At present, Liu Xue is still a minor, still attending school and unable to live independently. However, there are two problems in the determination of this case. First of all, to constitute the crime of abandonment, it is necessary to achieve "bad circumstances." "Bad plot" means that the victim was seriously injured and died because of being abandoned, and the victim was lifeless because of being abandoned. However, due to the aggravating circumstances that his biological parents did not establish crime of trafficking in children, the crime may have passed the statute of limitations.

In addition, some netizens think that Liu Xue may suffer from "smile depression". Zong Chunshan replied to the reporter that "smile depression" is not a very scientific concept, but he also explained that depression is tendentious and patients will feel sorry for the people around them. "He is more self-deprecating. He takes all the responsibility and leaves the good side to outsiders. You can't see his pain, you can't see his pressure, but actually his heart is quite painful.
