Mahavira Hall is the core of Yongquan Temple. There are three Sakyamuni statues called "Buddhas of Three Periods" in the middle of the hall, that means the past, now and the future. They are shaped in Ming Dynasty. The modelling of the statues are fine and smooth, showing grandfatherly eyebrow and kind eyes.

Two copper little fairy children of more than 1m high are standing in the hall. Their head with double overhand knot and their cheek with dimple, and each of them is holding a flat peach in one head and the other head is holding a lotus. They are the verdigris art masterwork in this early century.

In the back of the Buddhas of Three Periods, there is a Sansheng Statue with gold on the appearance. These three Avalokitesvara Statues are elegant form and elaborate work, that reflecting superb casting craft at that time.
