A variety of causes lead to the loss of a child’s life or disability, which may be an important reason for the country to liberalize the policy of two separate children. What do parents do when various tragedies occur? Parents are advised to come out of their sadness as soon as possible and visit a large reproductive center as soon as possible to see if there is any hope of having another child with the help of a doctor, and if possible, it is recommended to take effective measures to try to get pregnant as soon as possible. The prime reproductive period of women is very short, and some patients have lost their reproductive function when they are unmarried or unpregnant; therefore, women with fertility requirements must cherish their chances to have children and avoid the sadness of having fertility requirements two no longer have fertility. Example: A 4-year-old boy was scratched by a dog or a cat and received rabies vaccine at a local clinic, after which the child’s vision progressively declined, suspecting that the vaccine was the problem, and from then on the parents embarked on a slow journey to file a lawsuit, which was won 8 years later, when the child was 12 years old, ruling that the rabies vaccine was fake, but the child was almost blind and lost the ability to take care of himself. Mom had to return the same day to care for her blind son at every visit, no matter how late it was. Mom’s ovarian indicators in all areas reached a level of near failure and almost lost her reproductive function. Therefore, it is recommended that the authorities at all levels, strengthen the attention and assistance to similar families, and create opportunities for them to reproduce the rest as soon as possible, so as to reduce the occurrence of similar tragedies.
