What emotion did General Lao Wang of Jiangyin in Qing Dynasty express?

This poem is about the future of a weather-beaten and battle-hardened old general. The characters are lifelike, lifelike. The general in this song may be a veteran in the author's life, and he sympathizes with him. Perhaps it is entirely out of fiction, to pin their grievances without talent. This may be the author's own portrayal. Because Xiaoshan is also such a "beard", he indulged in subordinates in his later years and forced himself to serve others.

[translation]

There is an old general at the gate of the barracks. He is wearing a scarf made of ribbon. As soon as the wind blows a bunch of purple beards, the sword rustles, making the pattern on the sword box more clear and obvious. His mount has been useless for a long time, and the saddle pad is covered with dust. On the green grass by the river, a war horse is grazing leisurely. [2]
