Why did Guo Moruo attract so much criticism?

Guo Moruo is a very controversial figure. Since the development of the Internet, his criticism can be seen everywhere. He even wrote poems to flatter Stalin and marked "Zi and Guo Moruo" at the end of the poem.

First of all, it is undeniable that Guo Moruo is indeed a gifted scholar, and even Mr. Lu Xun has to admit it when he scolds him. He not only writes poems well, but also plays well, which has a certain position in the history of modern literature. In addition, he has also made great achievements in history, and most of the deciphered Oracle Bone Inscriptions is due to him. At that time, many literary giants held a positive attitude after the publication of his work Goddess, but his character was somewhat unsatisfactory.

The first is to attack Mr Lu Xun. At that time, he suggested that Lu Xun write with him to criticize the old times, and Lu Xun also agreed, but later he conversely said that Lu Xun was a feudal remnant, which disappointed Lu Xun. It is said that Mr. Lu Xun once thought highly of this literary youth, and he also touted Lu Xun. As a result, he turned around and caught Lu Xun, who had always been grateful to him, and completely changed his image. Lu Xun was very helpless and had to pay him back: talent hooligans.

On Stalin's seventieth birthday, Guo Moruo wrote him a birthday speech, which was full of flattery. There is a paragraph that reads like this:

The power of the atomic bomb is just a joke in front of you.

The threat of germ warfare is just a dream in front of you.

Your light and heat will turn the northern and southern oceans into warm currents,

Your nourishment will turn the Sahara desert into fertile soil,

Your wisdom will change rivers and mountains.

It is understandable to flatter great men, but Guo Moruo put "Zi, Guo Moruo" at the end, which is unbearable. Do you want this?
