Four Treasures of Hebei

They include the Great Bodhisattva of Zhengding, the Anji Bridge, the Liaodi Pagoda, and the Iron Lion of Cangzhou.

It was built under the direction of Li Chun between the years 595-605 AD during the Sui dynasty.

The double pair of openings piercing both ends of the arch spandrel, which as well as accentuating its lithe curvature, lightens the weight of the bridge and facilitates the diversion of flood waters by allowing them to pass through the auxiliary arches rather than pound against the spandrels.

In 1803, a storm toppled the statue resulting in damage to its snout and belly.

The bodhisattva was at some time removed for the value of its bronze; this could have happened as early as the reign of Shizong (r.+954-958), Emperor of the minor dynasty of Later Zhou, in his campaign against Buddhism.

It was cast in seven parts from the bottom up starting with the lotus stand and finishing with the arms, of which there are 42 in total.

The pagoda stands at a height of 84 meters (276 ft), resting on a large platform with an octagonal base.
