This is the place of practice left by the Jesuit Society (IHS) to the Portuguese and Chinese people, and its significance is extraordinary. The monastery is not open to the outside world, but it can be visited. The monastery is a cream-colored exterior wall with white patterns and dark green windows. Although it does not have the magnificent beauty of Rose Hall and Fengshun Hall on the outside, it has a beautiful Baroque dome, a luxurious pipe organ, a golden spiral column, beautiful mural inscriptions and reliefs under the altar "Last Supper".
