The Fengshan Gate, on the east side of the Fengshan Gate, spans the Middle River and is also built by Zhang Shicheng. Later generations called it Fengshan Gate because it was close to Fengshan Gate, it is the only ancient city gate in Hangzhou that has been preserved for more than 600 years. Fengshan Watergate Mountain is made up of two stone arches of different spans. The south span is more than 10 feet 3 feet and the north is 10 feet 7 feet. Between the two for the stone square gate gear, the rear of the gate gear has stone door molars, can open and close the gate. In the center of the top of each archway is a lockstone carved with a pan-dragon to lock the gate. The first floor above the city was built to protect against enemy attacks and to open and close gates to regulate the river. Unfortunately, the water gates were dilapidated and the walls of the city walls collapsed, and gates are now hard to find. In the 1980s, Zhonghe River was restored in accordance with the original water city, and a park was built next to it. In the park, there is a monument written by General Zhang Aiping, former Vice Premier and Defense Minister. In 2013, it was included in the seventh batch of key national cultural relics protection units.
