Introduction to Sanjin Academy: Sanjin Academy is located on the east side of "Shiwu Mountain Spring" and on the west side of "Garden in the Garden". As early as the Ming Dynasty, the great writer Jia Menglong had a praise saying: "The endless mountains are as powerful as a series of waves, and they are constantly drifting with the waves." Jia Menglong once built 18 rooms here for literary friends and poets to discuss poetry and essays. Later Jia Sanjin wrote books here, so it was called "Sanjin Academy".
