Of the forty-eight merchant guild halls that once crowded the river port of Wucheng, only one survived the fires of war. In March 1939, Japanese military forces set blazes that consumed seventy percent of the town. Yet the Ji'an Guild Hall, historically known as Hede Tang, escaped the ash. Its survival preserves the legacy of the Gan merchants who first established this trading hub on Renmin Road during the mid-Northern Song Dynasty. Between 1815 and 1827, these merchants rebuilt the hall on its ancient foundations, leaving a monument of brick, stone, and wood.

The surviving front entrance hall covers one thousand square meters. Its foundation of coarse, rammed sand and stone supports a two-story brick-and-timber frame. On the lower level, an inner screen wall divides the guest reception hall and its side chambers. Above, a wooden theatrical viewing stage rises toward an oval caisson ceiling decorated with elaborate wood carvings. Outside, a Huizhou-style gatehouse features carvings in stone, brick, and wood.

A pair of weathered stone lions guards the southern entrance. Above them, a cool, chiseled granite plaque bears the words 'Minister of Neo-Confucianism.' The early Ming Dynasty scholar Xie Jin inscribed these characters to honor the Southern Song national hero Wen Tianxiang. Flanking side doors bear the inscriptions 'Dwelling in Benevolence' and 'Following Righteousness.'

Designated as a provincial-level key cultural relic in 2006, the hall is now part of the China Migratory Bird Town tourism zone. Visitors can touch the ancient masonry, look up into the shadows of the carved ceiling, and hear the quiet echo of centuries of commerce.
