When Fan Zhongyan wrote Yueyang Tower, he had never been to Yueyang Tower at all, because his friend Teng Zijing was demoted to Yuezhou, Hunan in the spring of the fourth year of Qingli. One of the achievements during his tenure was to restore Yueyang Tower.
Fan Zhongyan has never been to Yueyang Tower, how did he write the story of Yueyang Tower?
In order to increase his popularity, he sent Fan Zhongyan a picture of Dongting in late autumn and asked him to help write an article (note).
And Fan Zhongyan grew up in Taihu Lake, and he may have also borrowed from the beauty of Taihu Lake, and finally made up this famous story through the ages with his own imagination.
