　　    The largest circular building in diameter in both Nanjing and Yongding — Shunyu Building — is located in Shiqiao Village, 3 kilometers away from the Hekeng Tulou Cluster. The outer diameter of Shunyu Building reaches 74 meters, with a total area of over 4,000 square meters, equivalent to the size of 10 basketball courts. This building has a total of 372 rooms; even if you stayed in one room per day, it would take you more than a year to stay in every room.

　　    Construction of Shunyu Building began in 1927 under the supervision of its owner, Zhang Qigen, and took 20 years to complete. Currently, the building is home to 40 households of the Zhang family, comprising over 250 people.
