Please help explain Deng Wusuicheng in Wen Tianxiang, thank you!

The heroic spirit of China is resistant to cold weather, and the country is like a broken arm, and the mountains and rivers are no longer connected. The saddest thing is what happened during the cloud opening period. (Here I contacted the treacherous court official's rebellion at the end of Jin Dynasty during the Kaiyun period in Wusui Chengguan. A few people will be concerned about whether to recover lost ground after death. I enjoyed the splendor of my life and ended up like this. Even though I accumulated countless wealth before my death, I was only a poor man. Such a narrow white ditch (which was the boundary river between Jin and Song Dynasties in ancient times) divided the country into north and south. Who can hold out until the end? (Here, it is not easy for Liu Xiu to hint at his worries about Song Jiangshan's vacillation after returning to China. )
