I have a younger brother, but my mother is afraid that we will not be filial in the future and wants another younger brother, and he is 14 years younger than me, but what should I do if I don't want it? I 14 years old.

You are at least fourteen years old and have your own opinions. If you have such an idea, you can talk to your parents, because if your parents want another little brother or sister, the sex can't be controlled artificially at all. Who will raise your brother when you are old? This is a very realistic question. You already have a younger brother. The key factor of filial piety is the child's family education. If the first two children are not filial, parents can ensure that their family education can ensure the filial piety of the third child. It is also an uncertain factor. Parents, why? Since you don't want your parents to have a younger brother or sister, talk to your parents like adults, and then let them weigh the pros and cons before making a decision. Although you have no decision-making power, you have the freedom to participate and make suggestions.
