Returning from Siming Lake to Liangnong, I woke up the doorman who was taking a lunch break and knocked on the door of Wugui Building. This second library in east Zhejiang (the first is Tianyi Pavilion) hidden in the alleys. During the heyday, there were more than 50,000 books in the collection, and it was named Wugui Building because of the 5 brothers in the same department. The second floor full of bookcases, and the third floor dark pavilion hidden by hidden secrets, were blocked by a small key at the staircase in the back hall of the first floor. No books are found, and the original smell of books is smelled. In the ancient town of Liangnong called Zhengmeng Street, find Wugui Lane, and walk along the alley to find it.
