Ruins of the Mosque Main Hall

　　  The ruins of the mosque main hall are located in the middle section of Dabeijie Street, Chengguan Town, Langao County, dating back to the Qing Dynasty. Constructed in the 24th year of the Jiaqing reign (1819). It originally covered an area of approximately 150 square meters, facing east with its back to the west. The original structure had a width of three bays (10.2 meters) and a total depth of five bays (14.85 meters), featuring a flush-gable roof with gray tiles and a post-and-lintel timber frame. The building no longer exists, but a new main hall has been constructed to its east. Inside the hall, there is one stone stele from the 19th year of the Guangxu reign (1893) inscribed with “Eternal Donation for Shop Houses,” as well as six plaques bearing Guangxu-era inscriptions: “Sincerity Never Ceases,” “Heart Upholds the True Faith,” “Profound Grace Like a Canopy,” “The One True Path,” “Hall of Scripture Studies,” and “Ancient Mosque of the True Faith.”
