There are two ferries from Zhangjiagang to Nantong, Sha Tong and Zhanggao. As soon as we crossed Sha Tong Auto Ferry, we arrived at Chongchuan District, Nantong. However, after crossing Zhang Gao's bus junction, you will arrive at the Evergreen Sand in Rugao. In Er 'an area, you can take a direct bus to Nantong city.
I think you must be from Jingang Town, Daxin Town and Deji area.
