What should I call my sister and brother?

If the woman chooses a word, the man can choose a word, or like my sister, two words and the same word can also be used. However, if the man wants to inherit the family business, it is best to choose a word that can shock the scene, such as Zhou, or consult some relatives, but it is best for you to choose it yourself. After all, the baby is yours. I hope you can choose the best one that sounds good and bodes well.
