Excuse me, I want to go to Qinhuangdao for about three days, and I want to go to Dongshan Bathing Beach, Sea Cruise, Shanhaiguan Happy Ocean Park, and Xin'ao Underwater World

Go to the sea cruise on the first day, go to Dongshan Bathing Beach in the afternoon, and go to Shanhaiguan Happy Ocean Park on the second day. It takes a day and you need to bring a swimsuit. On the third day, go to Xin'ao Underwater World, about half a day, and you can rest or play at the beach in the afternoon.
