Here is a country that has grown drastically in almost every area possible over the past few decades. China is huge and so are the opportunities that lie there.
In many places the cost of living is still cheap and much of the country’s authenticity is still intact. China is simply adding things. Things like malls, skyscrapers and entire cities. All these developments make China an interesting place to live for foreigners. It has a rich and traditional culture, yet most Western conveniences are widely available.
Local food is amazing and the landscape, partly due to the size of the country, is so diverse you’ll need years and years to explore it all. Snowy mountains, palaces and beaches; it doesn't matter what you have in mind for your leisure time; you probably won’t have to leave the country to find it.
The country’s strong, hierarchical culture can also by found at work. Your Chinese boss is probably not used to being questioned by someone younger and giving suggestions and ideas in a way that’s not offensive can be an interesting challenge. It’s important to ask a lot of questions and keep a close eye on the work that needs to be done, never assume anything.
