If Mao II didn't die in Korea, he must be the leader of PRC since 1976.
Most likely, PRC is under Mao III now. What China would be now?
Three things would surely happen:
1. Deng had no chance at all.
2. The GREAT leader, Xi Jinping, must be a slave of Mao II or Mao III and he has no chance to show his greatness at all. In addition, Xi Jinping can not serve Chinese forever.
3. China must belong to the great family of Mao. It is Mao's family to serve Chinese forever.
In one word, Qing dynasty died in 1911, but the whole system is there.
In my lifetime, I do hope that China can build a 現代國家管理體係. But it may never come.
