Is Macao prosperous?

Of course, Shanghai is the most developed and has the fastest economic development. It should be similar to Hong Kong. Xiamen is a little worse than Shenzhen. Although the development of Shenzhen is not slow, it has passed its best years after all.

As for Macao, it certainly can't compare with Shanghai and Hong Kong. I think what I said above is biased.

Macau is certainly very prosperous in many cities in China. But after all, it is a tiny place, and its development potential is not as good as that of big cities such as Shanghai.
