Get off and take bus 12 to Cangwu Green Park, and walk eastward for about 100 meters to Lianyungang. You must go to Huaguo Mountain, a famous national scenic spot. You can go out from where you live, or you can take the 12 bus to Huaguoshan. The student ticket for 50 adults is 100.
You'd better take a certain amount of food before going up the mountain. Other scenic spots include Taohuafang, Liandao Yuwan and Huangwo for three days. I suggest you go to Huaguoshan for a day, even the island for a day, and finally spend a day in the city or go to Taohuajian.
Liandao, you can take bus 106 in the urban area and get off at Lianyun District. There is a direct bus to Taohuafang in Liandao, or take bus No.3, and the terminal is Taohuafang.
There are pedestrian street and underground shopping mall Wanrun Commercial Street. Snacks can be found in the pedestrian street. Lianyungang Xiaowu cold rice noodles are good.
The ponds in Wanrun Street are also delicious. You can try walking street slowly. There are good Wanzhou grilled fish ~ ~
