The Great Shrine Hall is the main part of the monastic architecture. The Great Shrine Hall in the Jade Buddha Monastery is built on the terrace over one meter in height surrounded with carved stone balustrades. There is a stone lion on each pillar of the balustrades, small and exquisite in different postures. The hall is a two-storey imitation of royal palace of the Song dynasty. Under the upturned eaves hang bells ringing in chorus in breezes. The hall is seven bays in width and five bays in depth. In the middle of the hall there are three tall Buddhas, Sakyamuni in the center, the Buddha of Medicine in the east and Amita Buddha in the west. The Buddhas are all four meters in height and sit on the hexagonal support in the shape of lotus flowers. They look serene, their eyes are narrow and long, and look down with two ears drooping. All the Buddhas are gilded and appear brightly golden, solemn and serious.

Along the sides in the hall are twenty sculptures of the twenty devas. They are Buddhist guardians and symbols of good fortune that common people cultivate themselves with different kind and charity activities. They are in turn Indra, Vaisravana, Kinnara, Prthivi, Mohesvara, Laksmi, Guhyapati, Marici, Candra, Bodhidruma, Mahabrahman, Pancika, Hariti, Skanda, Virupaksa, Dhrtarastra, Sarasvati, Surya, Sagara, Yama-raja.

Behind the three Buddhas is a great painting of the island and Avalokitesvara. Avalokitesvara is a Bodhisattva of great mercy to help people in misery and hardship. According to the chapter on the Universal Door of the Wonderful Dharma Lotus Flower Sutra, if people are in the disaster of flood, fire, or war, they can be saved only if they piously chant the name of Avalokitesvara. Therefore, the faith in the Bodhisattva Avalokitesvara has a wide tradition among ordinary people.
