From the Longting down the highway, visit Cai Lunxuan, tickets 30 yuan, over 65 years old and military free tickets. Cai Lun, the official of the East Han Dynasty, was knighted as Longting Hou because of his invention of papermaking, and was forced to commit suicide because of his involvement in the court struggle, and was rehabilitated. Longting was his sealing place and suicide place, so he was buried here. Cai Lunxuan has a plaque written by Tang Dezong and Yu Youren, and a tombstone written by Mr. Zhao Puchu. Next to Cai Lunxuan is the Cai Lun Paper Culture Museum, where you can watch handmade paper.
