Siyuan Baoding was built in 2007 to commemorate the 10th anniversary of Hong Kong's return to China. Its appearance is based on the Dake Ding of the Western Zhou Dynasty. It is a three legged round Ding. Siyuan Baoding is 4.65 meters high and weighs 4.65 tons, implying that the distance from Hong Kong to 300 mountains is 465 kilometers. The diameter is 330 cm, which echoes the name of 300 mountains. Siyuan Baoding implies the friendship of the people of Jiangxi, Guangdong and Hong Kong to protect the source and bond with each other because of water.
