Evaluate Du Fu objectively according to history?

Wang Fuzhi was the first person to criticize Du Fu's poetic personality! He was also the first person to put forward the theory of "Li You Du Inferior". Wang Chuanshan scorned Du Du similarly, while Mao Zedong also praised Li and suppressed Du. Du Fu was neither an ideal model nor a handsome man in Wang Chuanshan nor Mao Zedong. But Du Fu is a great poet. This is the truth.
