At the southwestern edge of Tuanshan Village, Jianshui Dacheng Monastery stands against the base of a sloping hill. Built between 1723 and 1736 during the Yongzheng era of the Qing Dynasty, this two-entry courtyard complex began as a Buddhist sanctuary. Over decades, Han Chinese immigrants of the Zhang clan arrived, bringing their own beliefs. They placed the military strategist Zhuge Liang and the rulers Liu Bei, Guan Yu, and Zhang Fei alongside the Buddhist figures Maitreya and Wei Tuo. This physical arrangement reflects the practical spiritual alliances of Yunnan's frontier merchants.

Visitors ascend seven stone steps, an odd number chosen for auspicious alignment. The steps lead to elevated blue-brick Sumeru pedestals that support the timber-framed halls. These structures—the Front, Middle, and Main Halls, flanked by side wings—feature single-eave, hard-gable, and raised-beam designs. Overhead, rows of grey clay tiles shield the interior from the mountain weather, while tightly arranged dougong brackets support the heavy eaves.

The monastery's artistic peak rests in its eighteen gilded, openwork screen doors. Carved by local craftsmen, these wooden panels feature three-layer deep relief carvings. The lower sections display twelve flowing grass-script characters wishing for favorable weather, national peace, and long life. These doors stand exposed to the open air, their gold leaf catching the shifting daylight.

Directly outside the entrance, a circular ancient well provides a constant connection to daily life. For generations, villagers gathered here to draw sweet, cold water that never ran dry. Inside the halls, remnants of later historical periods appear in faded slogans painted over older murals. In 2013, the monastery received national protection as part of the Tuanshan Residential Architecture Group, preserving a physical record of cultural migration and architectural adaptation.
