Gongbei (Islamic architecture)
Gongbei (Chinese: 拱北; pinyin: Gǒngběi; from Persian: گنبد gonbad, meaning "dome", "cupola"), is a term used by the Hui and Uyghur Muslim populations of China in the Northwestern region to indicate an Islamic shrine complex centered on the grave (qabr) of a Ṣūfī Muslim murs̲h̲id ("master") or walī ("saint"), typically the founder of a menhuan (a Chinese Ṣūfī ṭarīḳa, or "saintly lineage"). The grave itself usually is topped with a dome.
