Pearl Spring, Karst spring in Jinan, Shandong, China

Pearl Spring (Zhenzhu Quan) is an artesian karst spring in a square pool enclosed by a stone fence at 1 Yuanqian Avenue, Lixia District, Jinan, Shandong. Bubbles rising from the pool floor give it its name, and the outflow runs through a canal into Daming Lake. It is one of Jinan's four great spring groups, with Sanshui, Xiting and Chu springs among its neighbours.

The spring was incorporated into the garden of Prince De in 1466. The prince's mansion was destroyed in war in 1638, and in 1667 Zhou Youde, governor of Shandong, rebuilt the site as the Xunfu Yamen; the provincial government stayed by the spring until the Japanese occupation of Jinan. Since 1979 it has housed the Shandong Provincial People's Congress.

The spring's name comes from the bubbles rising from the pool bottom, which look like strings of pearls. It was enclosed in the garden of Prince De in 1466, and the surrounding compound later served as the Shandong governor's yamen and provincial government seat. The spring group also includes Sanshui Spring, Xiting Spring and Chu Spring.

The spring sits at 1 Yuanqian Avenue in Lixia District, in the old centre of Jinan south of Daming Lake. The office compound and the sightseeing area are separated, and visitors can enter the spring garden by buying a ticket. The pool is square and enclosed by a stone fence on all sides, with water flowing off through a canal into Daming Lake.

The spring sits at the bottom of a square pool enclosed by a stone fence on all sides, and its overflow runs off through a canal into Daming Lake. The bubbles rising from the pool floor are what gave the spring its name.
