Independent travel in Cairo, I became friends with a scammer

Cairo, an ancient and mysterious city. Most of the buildings are earthy yellow, with a strong Arabic style. There are also a few Western-style buildings. Independent travel is suitable for this area with Western-style buildings, there are spectacular buildings such as the National Bank of Egypt, but do not take pictures of official buildings. They are friendly to Chinese people, and people on the street will say welcome to you at any time, and children will be curious to follow you around. In the scenic area, do not accept the kindness of strangers, he just wants to make money from you... Egypt is a tipping country, be mentally prepared, they don't ask for much, but it's best not to have a psychological gap.
