What role does the article "Zhicai Birthday" play in describing the hot weather environment?

Describe the function of "hot weather";

① Render the atmosphere to enhance the sense of reality. "On a red day, there is not a cloud." How can porters travel in such weather without complaining?

(2) Contrast psychology, form and spirit. "When all the soldiers looked at that day …", the weather was so hot that Jun Jian's resentment, anger and disappointment all appeared.

③ Change the scene and develop the plot. "The sun is like fire", and all the soldiers are thirsty. The folk songs sung by Bai Sheng just entered the ears of all the soldiers, and another scene began to promote the plot.

Ask again if you don't understand. I wish you progress in your study and go up a storey still higher! (*^__^*)
