Dongguan Keyuan, Shunde Qinghui Garden, Panyu Yuyin Mountain House and Foshan Liangyuan are collectively called the four famous gardens in modern Guangdong.

On three acres (2,204 square meters) of land, pavilions, landscape bridges and trees, halls and courtyards are all available. Carved from wood, stone and blue bricks, but the architecture is very particular. Window carvings, railings, beauty brackets and even floors are all in different styles. Its layout is patchy, interconnected, winding and confusing. The keynote is that there is a scene in the empty place, the sparse place is not empty, the small place is big, dense but not urgent, quiet and interesting, quiet and fragrant. In addition, the decoration is fresh and elegant, occupying water to grow flowers, which is very rich in southern characteristics and is a treasure of Guangdong gardens. Zhang, the founder of Keyuan Garden, joined the army with a pen, and the official visited Jiangxi as an envoy. He was proficient in everything and invited scholars to get together, making Keyuan one of the cultural sources of modern Guangdong.

Nowadays, Keyuan has become a national key cultural relics protection unit, and it is more lovely after continuous improvement.
