Guts is purely fictional. It's a concept or character that exists within the realm of imagination and creative storytelling rather than being based on reality.
There was indeed a classic poem in " My Leader, My Regiment " that went like this:
"Oil seller monopolizes the top courtesan."
The oil seller monopolizes the flower
For a moment, there was something in the sky.
Cold autumn, lonely spring
Who can share my joy?
This poem was about a woman whom the protagonist Zhang Lixian met during the war. Her name was Leng Qingqiu, and she was a beautiful courtesan. Zhang Lixian wrote this poem after talking to her.
The language of this poem was concise and clear, describing the relationship between the oil seller and the courtesan, as well as the beauty of the courtesan and the loneliness of the cold autumn. This poem also showed the emotional state of people during the war described in the novel, expressing the loneliness and helplessness that people felt when they faced difficulties during the war.
I'm not sure if the TV station is broadcasting My Leader My Regiment now because the deadline for my knowledge is 2021, but I can find the broadcast resources of the play on TV or on the Internet. If you want to know more about the drama, you are advised to search for relevant TV stations or online platforms or consult local media staff.
