Catholics and Protestants in China divide themselves between "legally registered churches" and "nonregistered churches."
The Catholic communities of the “nonregistered churches” are called the "underground" church because they operate independently of the communist government-run religious institutions and claim a different historical affiliation.
Photographer Cristian Martini Grimaldi visited an underground community in Qingdao, Shandong Province, to report on how the community expresses and witnesses its faith.
