中國的選擇是-work hard and watch with the perspective of history

Empires come and go; China stays.  This is the "China Problem" that has been troubling many Western historians.

There is no point of actively replacing US.  US serves its function (and it gets greedy lately, demanding more from its service in maintaining and securing the international trade platform) and it is a factor for postive human progress in the long run. 

Always keep that in perspective.  Cheering for its demise is VERY short sighted.
