Generally speaking, the ancients had a cloud, and Guanyin sent a son, which means that the goddess Guanyin sent a son, which means to give it to a devout person.
However, in modern science and technology society, it is really fate to have children. Personally, I think it really doesn't matter if two people fall in love. So don't be so concerned about having a son and daughter.
Family harmony is the most important!
