How does Deng Yueyang Tower write about scenery?

This poem uses the technique of borrowing scenery to express emotion. The sentence "There is Wu in the east and Chu in the south, which shows that heaven and earth are floating endlessly" describes the magnificent scene of Dongting Lake: the vast lake separates the ancient boundary between Wu and Chu, and the sun, moon and stars seem to be floating in the lake. The magnificent and wonderful scenery of nature sets off the poet's broad mind. Although the poet is poor and sick, he still cares about state affairs, setting off the poet's broad mind!
