What are the differences and purposes of Lu Xun's three descriptions of appearance? What kind of person can we see Lu Xun?

First description: You can only vaguely recognize the shape in the dark: you wrote a gown (because of the color) and a cigarette holder (because of the fire).

The second description: at close range, you can see clearly; Write face, inch hair and beard. These three things all capture the characteristics. Straight and strong hair and straight beard are the characteristics of Lu Xun's image, while yellow and white face is a sign of fatigue.

The third description: face to face, can be carefully identified. The first two general paintings are still face, inch hair, Hu Shun, gown, cigarettes and drinks, but they are more detailed and specific.

The first purpose is to pave the way for the following understanding of Lu Xun.

Write the temperament of the character for the second time.

For the third time, the image of a soldier whose health was damaged by overwork was reproduced.

Thin, but full of energy, although physically exhausted, but still insist on fighting the enemy-selfless work, tenacious fighting spirit, full of energy, showing his resolute and strong character.
