if mine,i will chooes Singapore.

Singapore is my favorite! If you like beautiful and tropical and clean and multicultural.  Good government cares about the welfare of people _and_ business, not just business like China, far less corruption than China. Easy to get around speaking English, first rate universities and hospitals, plenty of shopping too of course. Maybe more shopping deals in HK. Very expensive to live there tho, more than the US, but you can find reasonable hotels if you visit.

Shanghai and Hongkong are unpleasantly full of people.So,i think those city aren't a good place to live in the city

Egypt is the best :D
