Which kind of leaders China needs?
I am not sure, but China needs a leader who understands China and the world. He should be able to lead China to be a more open, more free, and wealthier country.
I don't expect China can be a democratic country in 5 years, or in 10 years, or in 20 years, or even 50 years. China has a rich and complex history. China needs a group of strong leaders or a clever dictator like Deng. But the leaders should be wise.
Xi Jinping understands China, mostly the bad part. He knows how to control Chinese. He is a good student of Mao.
But he has no idea if we live in 21st century or 19th century. I mean he does not understand the world.
He wants to be the 2nd Mao or the 2nd Marx. However, the theory of Marx was proved to be wrong in 20th century. Mao's thought is basically the Chinese emperor's ideology. Neither Marx nor Mao is a good model.
Deng did some good work and he is the Washington of China. Unfortunately, China has too many yuan shikai. Most likely, Deng's legacy will be buried by Xi Jinping (actually, Xi already tried to bury it).
