Question

Probably to make others still believe she is a gay male. ┑(￣Д ￣)┍

But why?

I dunno ┑(￣Д ￣)┍
The author just likes making things loopty loop

More easy to make a connection
Maybe

Perhaps to make the mother not feel ashamed? The fact that the mother lied about the gender of her child to the father for money would probably cause her to get a lot of hate from external and internal sources. So maybe it would just be better to continue living as a man and telling only a few people of her true gender than to be humiliated and isolated by society? Although we see the women as the victims, ultimately the father would be seen as the true victim in newspapers and rumors ext.

Fu Jiu uses her new identity to begin her old work as a hacker, however, it is common knowledge to Qin Mo (who used to hunt her formal self with the international police) that the original hacker, Z, is a woman.

She keeps pretending to be a man to create distance from her past persona as well as from Qin Mo. As their relationship develops she believes that she will always want to stay with him and that he will do whatever it takes to keep her if he knows she is a girl.

Fu Jiu however does important work in the gray areas of the law to gain justice for the underdogs of the world through her hacking. While Qin Mo is a former consultant for the international police and believes that even though Z has good motives the ends do not justify the means. Fu Jiu believes that if Qin Mo finds out what she does in her spare time he will try to reform her and failing that (which she knows he will), arrest her.

Having a super straight guy having to overcome what he believes to be an aberrant sexual desire creates a shield. Though honestly not a very good one. He eventually says screw it to caring what the world thinks and begins to actively seduce Fu Jiu into "becoming gay".

When he does find out that she is a girl and the relationship develops in that direction the world just thinks they are gay for a while.

If you want a better answer than that you will need to read the novel.

Personally I also never thought there was much reason to continue pretending to be a guy. It just makes more and more trouble for everyone and there is never a lot of exposition on why Fu Jiu's mother thought that disguising her daughter as her son was a good idea.

It can, however, be inferred that it has to do with the mistress having a son as well as the financial status of the Fu's company as the time of the kid's birth. Fu Jiu and her half-siblings are only a couple of months apart and had Fu Jiu's mother had a divorce and her father married the mistress, when Fu Jiu was just born he would then have become the illegitimate child.

In the book she wants to get even with the father and half siblings plus not out his mom for fraud
