Falling red is easy to remind people of the passing of spring, the passing of good times in life, the fading of youth, the departure of friends and even the passing of all good things. The disappearance of a beautiful and fresh life will certainly cause bursts of sadness in people's hearts.
For example, Du Fu's "On Going Downstream": "It is common at home, and Cui heard it before. It is a beautiful scenery in the south of the Yangtze River. " On the surface, this poem describes the surprise of meeting, but in fact it is full of emotions. This is of course reflected in the comparison between the past and the present, and all of them are concentrated on the word "falling flower season". In retrospect, Du Fu and his friends were young, high-spirited and ambitious, and the Tang Dynasty was also in full swing. Nowadays, poet friends have gone through hardships and live in Jiangnan. They have reached the "falling flower season" of their lives. After the "An Shi Rebellion" in the Tang Dynasty, the river gradually declined, and it also reached the "flower falling season". The feelings of life experience and the hatred of home and country come to mind together, so why not?
