Nagato, Changxin Hall, Zhaojun Hall and Tongquetai are the themes of the four palaces. What do Nagato and Changxin mean respectively?

1. Nagato, the name of the Han Palace. Empress Chen, Emperor Wu of the Han Dynasty, once lived here after falling out of favor. According to legend, Princess Qianjin, the mother library of Queen Chen, was once hired to write a poem "Changmen Fu" for Queen Chen, which was very touching. In the classical poems since the Han Dynasty, the theme of "Nagato's resentment" is often used to express the sadness of losing the imperial concubine.

1. Complaint against Changxin Palace by Ban Jieyu

Ban Jieyu is the empress of Emperor Han Cheng, and before Zhao Yanfei entered the palace, Emperor Han Cheng was her luckiest. Her father is Ban Kuang, who galloped on the battlefield in the later period of Emperor Wu's attack on Xiongnu, and made great contributions.

Poetry was written from the moment I entered the palace until I felt sorry for myself, cherished my feathers and refused to be prosperous. I follow the example of ancient boys and girls, and I am willing to live in the palace for a long time, with a lonely lamp reflecting the wall and the room cold. When I think of my old love with the emperor, I don't feel tears and feel deeply grieved. Day after day, night after night, I mercilessly swallowed up the colorful years, and finally only wrote. Full of infinite sadness and gun feeling, people can't bear to read.
