Introduction to Gongde Archway: Gongde Archway is the north gate of East Lake. It was built in 1519. At that time, my country's garden construction had formed a certain pattern, and the north gate was a must-see. Wang Ren, then the prefect of Fengxiang, built an archway to complete the East Lake garden scenery and personally inscribed a four-character plaque with the words "Quiet Shadow of East Lake". On the left side of the north gate, there is a stone faucet with an open mouth spitting water, called "Cang Shi Chi", which is the source of the East Lake water flow. The Cangshi Chi mentioned in Su Dongpo's poem "East Lake" refers to it.
