Situated in the Miaodao alley of Da Bei Street in Changzhi, Shanxi Province, the Lu'an City-God Temple, founded during the Yuan Dynasty, stands as one of the most significant and well-preserved temple complexes dedicated to the City God in China. Covering an area of 12,229 square meters and featuring a total floor space of 5,175.03 square meters, this temple holds a rich historical legacy.

Lu'an City-God Temple, facing north to south, is organized around a central axis stretching 408 meters from south to north. The temple's architectural ensemble follows a sequence that includes the Six-Dragon Wall, Hong Gate, Wooden Building, Stone Building, the Mountain Gate, the Double Pavilion (Xuanjian Building), the Opera Stage, the Offering Pavilion, the City-God Hall, the Sleeping Quarters, along with side halls, corridors, and other structures.

In recognition of its historical and architectural significance, the temple was included in the fifth batch of national key cultural heritage protection units by the State Council of China on June 25, 2001.

A highlight of the temple is the traditional annual temple fair held on the 15th day of the fourth lunar month, which centers on the veneration of the City God, an ancient deity believed to protect cities and their inhabitants. On this special occasion, devotees offer tributes and burn incense in the hope of securing the City-God's blessings. To honor the deity, lively performances, including traditional opera, are staged to entertain the City God. As the event draws crowds, it naturally attracts merchants and peddlers who set up stalls, creating a bustling atmosphere.
