May be illegal. Parents are the legal guardians of children, and it is also the responsibility of parents to raise children. If you can't take care of the children directly because of work or for some reason, it is also feasible to temporarily give them to relatives for help, but the guardianship responsibility has not been transferred. If the child is directly given to someone else for raising, the law is not allowed unless the adoption and adoption procedures are handled. The adoptee must also meet the conditions prescribed by law before going through the adoption formalities. Article 2 of China's Measures for the Registration of Children Adopted by Citizens stipulates: "China citizens who adopt children in China or terminate the adoption relationship by agreement shall register in accordance with the provisions of these Measures." Article 4 stipulates: "The parties to the adoption relationship shall personally go to the adoption agency to go through the registration procedures for the establishment of the adoption relationship." . In addition, Article 5 of the Law stipulates: "The following citizens and organizations can be adopted as adopters: guardians of orphans, social welfare institutions and biological parents who have special difficulties and are unable to raise their children". Of course, not everyone can be a legal adopter. Article 6 The qualifications of the adopter are as follows: "The adopter shall meet the following conditions at the same time: at least 30 years of age, capable of raising children, suffering from diseases that the hospital has explained cannot be pregnant, and childless." In addition, it should be noted that the children who are put out for adoption must be under 14 years old, and the adoption relationship without any of the above conditions has no legal effect. Therefore, not everyone can give their children samples to others at will. Parents should stop giving their children up for adoption without knowing it, because adoption without relevant procedures is legally invalid. If it hurts the child, it may also be suspected of abandonment and bear criminal responsibility.
