Wangjiang Gate is one of the top ten ancient city gates in Hangzhou. Wangjiang Gate is the ancient southeastern city gate of Hangzhou. It was built in the 28th year of Shaoxing in the Southern Song Dynasty. To the east of the gate is the Maoshan River Caoqiao Gate. Destroyed at the end of the Southern Song Dynasty. At the end of the Yuan Dynasty, the city wall was rebuilt in the 19th year of Zhizheng Dynasty, and the east city was expanded for three miles. A gate was built here and the name was changed to Yongchang. Because the stool tower could overlook the river tide, the name was changed to Wangjiang in the fifth year of Emperor Kangxi of the Qing Dynasty. Outside the gate, there are fields in Jiangtu. Villagers grow vegetables as a profession. Most of the vegetables transported to Wangjiang enter the city through this gate, so there is a saying that "the vegetables outside Wangjiang gate are loaded with children". In the early Republic of China, the city walls and gates were demolished due to road construction. Wangjiangmen is also called Caoqiaomen, "Caoqiaomenwaicaitaner", which refers to the vegetable farmers in the vegetable fields outside Wangjiangmen. In order to let future generations understand the changes in the city, a monument was erected at the old site to commemorate it.
