Thanks! I will tell them your well-intentioned and sound advice.
1. Of course, any well-known country would probably be fine, even without being there.
For example, Australia, New Zealand, the five Nordic countries, Western Europe, UK, US, Canada should be fine. They are so multi-faceted that someone will not be "screwed" if they move there and find out they do not like it.
These people were never so daft as to defect to a place like Vanuatu or those smaller island countries.
2. Perhaps they are trying to think too many steps ahead.
a. First, simply pick an education program they want. For example, that masters in Finland.
b. Second, spend the 1-2 years living there, seeing if you want to trade a life in China for a life in another country.
c. If it is important, fight for it. Immigration to the five Nordic countries often takes 5-10 years and language requirements, but can be worth it.
