Initially constructed as the south entrance to a sanheyuan, the gatehouse is protected as a historical site in Taichung.

[1] The Lai family were one of the earliest Han Chinese settlers in Taichung.

Originating from Pinghe County, Fujian in mainland China, the family settled in what is modern-day Beitun District.

[2] In 1898, a member of this family, Changrong Lai (賴長榮), moved from Touzhang to the north to the current location, building the sanheyuan known as "Huaidetang" (懷德堂; Huáidétáng).

[1] In 1924, the family decided to rebuild the southern entrance according to a feng shui specialist's advice.
