Lángfāng Qīngzhēn Sì was built during the Qing Dynasty and is one of the most representative Islamic architectural groups in North China. The red walls and gray roofs harmonize with Arabic geometric patterns, and the octagonal minaret points directly to the sky. The stained-glass panels on the minaret cast colorful reflections in the sunlight. The main hall’s dome utilizes “dié sè gǒng” (layered color arch) craftsmanship, with sixty-four archways layered sequentially, and the golden “mihālabū” (prayer niche) in the center is solemnly devout, witnessing the worship rituals of Muslims throughout history.
