Teng and Fan Zhongyan meet again in Yueyang Tower.

There is a Yueyang Tower near Dongting Lake, with boundless blue waves. When you climb the Yueyang Tower and look at the lake view, you suddenly feel that there is a magical energy between Tianshui, which impacts your vision. No wonder literati and poets of all ages chose this place to express their feelings in poetry. However, Yueyang Tower is not only famous for its Dongting landscape, but also because Fan Zhongyan, the exiled Fuzheng Minister (equivalent to a powerful deputy prime minister), wrote an essay "The Story of Yueyang Tower" at the request of his classmate and exiled state official Teng, which attracted the attention of officials all over the world for thousands of years. Fan Zhongyan and Teng are both scholars. After they became officials, they were all remonstrators on the platform. Because Tengkou was outspoken, he told Emperor Injong in the last court: "If you live in the palace, you will linger on the famine feast, and you will win more in the near future. If you decide to do something, you won't hold on to the sacred embrace. " So, we have sinned against Injong. Injong was furious, denounced him for his nonsense, demoted him to the court, and made Fengxiang House the magistrate. On the occasion of the political reform, Teng was impeached for automatically misappropriating funds from the small treasury. Fan Zhongyan resigned rather than protect Teng, and finally saved Teng, but Teng was demoted again and went to Yueyang as a magistrate. Teng Amethyst is smart and good at management. After he came to Yueyang, he made great efforts to develop industry and commerce, attract investment, build public facilities and set up schools by taking advantage of Yueyang's strategic location, which promoted Yueyang's economic development in one fell swoop, transformed Yueyang's old appearance, won the hearts of the people, and raised funds to rebuild Yueyang Tower. At that time, this building was the place where officials from past dynasties welcomed in and sent out. Teng is gratified by his achievements in front of the building and indignant at his demotion. His mood is very complicated. He sent a book with an autumn color map of Dongting, and asked Fan Zhongyan to write a note for Yueyang Tower. After receiving the letter, Fan Zhongyan was afraid that Teng would get carried away and get into trouble again, so he advised Teng to have the mind of "taking the world as his own responsibility" and not to care too much about personal gains and losses, but to write down the famous book Yueyang Tower.
