"Wei Wei, I have got a set of uniforms here that would help you, but what about your hair? What are we going to do? It would certainly expose who you are!"

He knew Su Wei Wei was someone who wanted to keep her life private no matter what kind of scenarios she got herself involved in. And it was the same thing with Huo Shen, he didn't want her to be exposed out there.
"Ooohh! Huo Zheng, find someone who could buy a lace wig for me and it should be a little bit blonde, and also a few silicons I can use to cover up my facial features... I don't want to go around with my real facial features." She didn't want to be exposed, she still needed her private life to stay intact without disturbances, without knowing her, she could live and chat with anyone and go everywhere without the worry of getting her identity exposed.
