Translation: It is often found that it is strange, and there is a stagnation of worry, anger, and resentment.

Often it is strange to find out that there is a stagnation of worries, feelings and anger, which arises from the thorns of resentment

The thorns of resentment: the rise of resentment and sarcastic thoughts.

There is a stagnation of sorrow, emotion and anger in the heart. These emotions are transformed into poems, that is, they are placed in resentment and irony, expressing the sighs of the widow who chased the minister, and writing out the feelings that are difficult for people to express in words.
