What Teacher Daewoo said may not be very suitable for now, so I won't talk about Hong Kong. The biggest problem in the United States is global taxation, and taxes are indeed too high. For Chinese friends, the best and easiest option now may be the Singapore EP, and if conditions permit, a developed country PR that exempts non residents from global taxation can be configured. The United Arab Emirates is good, but it requires obtaining a Work Visa/Residence Visa through registering a company, and there are many unfavorable conditions such as language, living habits, etc. Singapore is relatively the simplest and should have the lowest cost.
