What are the four wonders of Yueyang Tower?

Yueyang Tower, rebuilt by Teng, has the largest scale and the most complicated structure, with four octagons and twenty-four eaves. Later, Teng asked Fan Zhongyan, a great calligrapher at that time, to write "The Story of Yueyang Tower" and seal it.

People call Teng Xiulou, Fan Zuoji, Su Shoushu and Shao Zhuan the "Four Wonders in the World" and set up the "Four Wonders Monument" to commemorate them, which has been well preserved so far.

In addition, Teng also sent someone to carve the "Four Unique Screens" from this "Four Unique Monuments", which clearly recorded Fan Zhongyan's "Yueyang Tower".
