Can I choose to have boys and girls?

Why not? As long as you can find the Qing palace watch, you will have everything except sexual intercourse. The so-called Qing palace watch refers to the list of boys and girls born in the palace to the people during the Qing Dynasty. You can usually find it in the yearbook. If you can't find it, haha. I have it here. Please invite my guests and I'll give them to you. It is very accurate. My son was born on the list.
