Introduction to Hejiang Pavilion: The last building in the academy is Hejiang Pavilion, which was first built in the Zhenyuan period of Tang Dynasty and was built by Qi Ying, the governor of Hengzhou. In subsequent dynasties, the buildings on Shigu Mountain were repeatedly abandoned and rebuilt, and Hejiang Pavilion was among the must-have buildings. Han Yu was demoted and went south. He passed through Hengzhou and visited the pavilion. He left behind his famous work "Inscribed on Hejiang Pavilion and Sent to the Governor Zou Jun". The whole poem is composed of 200 words, rhymed to the end, and completed in one breath. It was highly praised by later generations of literati and scholars. Many people followed the rhyme and harmonized it. Hejiang Pavilion has also become famous for this masterpiece through the ages.
