Jin Temple, a once-in-a-millennium garden! Its architectural artistry is breathtaking. It's China's oldest extant imperial sacrificial garden and the largest, oldest, and best-preserved ancestral temple-style classical garden in existence. The Holy Mother Hall is a towering achievement of Song Dynasty architecture. The eight wooden dragon-carved columns in front of the hall are lifelike, and their beams, constructed with a "three-column structure for six rafters" (nipple beams) are the only extant example of a Chinese ancient building conforming to the palace-style structure prescribed by the "Yingzaofashi" (Construction Code). The Yunuma Flying Bridge is China's earliest cruciform ancient bridge, with its unique shape and considered the prototype of the modern overpass. The Offering Hall is my country's only extant building combining a hall and pavilion, featuring an ingenious beam arrangement that is both economical and sturdy.
