Yangzhou salt merchants began to build gardens, and still retain many excellent classical gardens, among which Geyuan, located in the north corner of the ancient city, has the longest history, the most complete preservation and the most artistic value. Geyuan was built in the 23rd year of Jiaqing in Qing Dynasty (A.D. 18 18) by Huang Zhijun, the general manager of salt merchants in Huaibei. Geyuan was awarded the third batch of "National Key Cultural Relics Protection Units" by the State Council in 1988. The garden wins with bamboo stones, and even the word "Ge" in the garden name is half of the word bamboo. To combine with all kinds of bamboos in the garden, the owner's interest and thoughts are in it. In addition, it got its name because every three bamboo leaves at the top of the bamboo can form a "grid", and the shadow on the white wall is also a "grid".
