Why does my baby have to be named Zhihu after my husband?

Since ancient times, it is a tradition that children take their father's surname.

Coincidentally, the paternal surname only retains the imprint of the Y chromosome. The significance of this is that, for example, if you find Cao Cao's tomb and you want to verify whether the owner of the tomb is Cao Cao, you can find some people named Cao to compare the Y chromosome. However, if a bunch of boys take their mother's surname, the surname itself will eventually lose its meaning.

Although it doesn't affect this girl's mother's surname, what do you want to do if we say that several generations of girls take their mother's surname and inherit from their original grandfather?

If you want to pursue women's rights, don't do such trivial things.
