Introduction to the main hall of Qianjin: The wooden screen of "The Biography of Qu Yuan" written by Sima Qian hangs on the screen wall of the main hall of Qianjin. There is an octagonal caisson on the ceiling and a relief sculpture of two dragons playing with beads in the interior. In the Danqi between the front hall and the middle hall, there are two ancient osmanthus trees that are more than 200 years old, with lush branches and leaves.
