How to get from Changchun to Dandong Zhang Dao? What kind of car? And then transfer to what ship? how much is it? There are points. thank you

I advise you not to go. . I have just been there. There is no point in coming back. . The round trip from Changchun to Shenyang is about 1200 km. . Go to Shenyang South Ring Expressway and run Dandong Expressway. Go through Dandong and get off at Donggang. There are signposts when you get off the highway. . There is only one way, and you will walk well. About 20 kilometers walk, there is a small town called Beijingzi. . There is a small port in the town, and a boat goes to see the tide once a day (50 tickets). Without the tide, the boat can't get in. Usually leave around 8.9 in the morning and return at 7.8 in the evening. . This island is not as good as you think. . I just live well. . They are all sea view rooms. . The most expensive one is 300 yuan, and the other one is 30 yuan for a bed. . There is nothing to eat.
