What are the descriptions of Lu Xun's physical characteristics?

Lu Xun's appearance is described as follows:

Lu Xun is a serious intellectual. Mr. Lu Xun has always been used to wearing a long gown and often has a cigarette in his hand. His bamboo fingers clung to the brush as if to write down all the injustices in the world.

On his closed lips, the most striking thing is his black beard, which is as thick as words written in thick ink. A pair of sharp eyes look straight into the distance, and it will penetrate all clouds and seek truth. There is a cold temperament everywhere.

Artistic features:

Lu Xun's novels are unique in material selection. In the choice of themes, Lu Xun reformed the mode of choosing only "brave men, thieves and robbers, monsters and immortals, talented people and beautiful women, followed by prostitutes and lackeys" in classical literature, and created two major themes of modern literature with "for life" as the enlightenment purpose.

His materials "are mostly taken from the unfortunate people in the sick society." Lu Xun has an extremely unique vision in dealing with these subjects. When observing and expressing his hero, he has his own unique perspective, that is, he always pays attention to the mental "diseases" of intellectuals and farmers in the "sick society".
