It means that now that you have a daughter, you will have another son in the future, right?
I think your concept is incorrect. Giving birth to a son will happen in the future. If you want to name your daughter, just give it a good name. Why should you accommodate the name of a son who may be born in the future? No one requires you to have similar names, as long as they have good meanings.
Or do you want to use your daughter’s name to recruit a son for you? Like "recruiting a younger brother" or something like that. This is all superstition, and it doesn't mean that if a daughter is named "Zhao Di", she will really have a son. What kind of era is it now? Men and women are equal. Besides, I think daughters are better. Raising daughters is less stressful, and raising daughters is caring and filial. I suggest you straighten your mind first and seriously consider what name your daughter should be named, and don't think about your son in the future.
Back to the question, what is a suitable name for your daughter? Although the influence of names on people is not particularly great, the quality of the name still has a certain impact, so it cannot be too casual. A girl should be generous, give people a good impression, be unconventional, not pretentious, and have a good meaning, which will be good for her life.
