Located beside the Xiao Family Residence, Buyue House takes its name from the poetic scene of moonlight once reflected in the small river in front of the building. Originally serving as the Xiao family’s private gate tower, it also functioned as a study known as Yuying Studio and a small book repository. The roof features elegant, upturned swallowtail ridges, while the walls are adorned with clay reliefs of egrets and lotus flowers symbolizing “continuous success in the imperial examinations,” creating a refined and scholarly atmosphere.

Buyue House also bears witness to the dramatic history of the Yiwei War in 1895. During that time, Xiao Guangming, a leader of the Xiao family, led local militia forces in resistance against foreign invasion. Bullet marks preserved on the walls, along with three reinforced door bolt holes added for defense, continue to record those courageous years of protecting the homeland. Walking to the rear of the tower, visitors can also see the distinctive “jar wall” constructed from stacked wine jars, which not only forms a unique architectural feature but also reflects the prosperous period when the Xiao family first built its fortune through wine making.
