The "Ershui Beizaitou Zheng Family Ancient House" has a history of over 90 years and is a historical building in Changhua County. It is a well-preserved traditional Fujian-style compound house in the Ershui area, with a three-entry, three-courtyard, and eight-protected dragon scale. The settlement is backed by the Bagua Mountains, and in front is a feng shui pool. The ancient saying used to describe the scale of large houses, "a large house with nine rooms and five wings, three halls and 102 doors, a fish pond in front, and a fruit tree behind," is a vivid portrayal of this traditional large house, and the Zheng Family Ancient House is a perfect example of this.
