I suggest you start from the urban area to the west in the direction of Gushan and Mawei, cross Gushan Tunnel, then take National Highway 104, and take Shenhai Expressway and Ningde direction at the entrance and exit of Mawei. If you are not familiar with it, you can also start from the urban area, go south, go to the Fuzhou connection line of Shenhai Expressway at the entrance and exit of Fuzhou, and then turn to Shenhai Expressway and Ningde. But it's a long way and the time difference is not too much. Go straight on Shenhai Expressway to Yongtaiwen Expressway in Zhejiang Province. After passing "Linhai North", turn right into Shangsan Expressway, go to the end, turn into Hangzhou-Ningbo Expressway, cross the entrance of Hangzhou-Ningbo Airport, and then turn into Hangzhou Ring Expressway, about 1 km. There is a "Xiasha" entrance across the Fifth Qianjiang Bridge in Shanghai.
