Which of the four coastal cities, Qingdao, Dalian, Xiamen and Lianyungang, is more fun?

Gulangyu Island opposite Xiamen has Longzhuang Garden, Piano Museum, Sunlight Rock and Underwater World. I didn't have to buy it in the past, but I will buy a ticket when I come back. The music square of the ferry is also good. I heard that there will be a fountain during the festival. You can go there to play and don't fall into the sea. You can also go to Huandao Road, where Taiwan Province Folk Village, Fufeng Village and Strawberry Garden made their debut. Shiwan Botanical Garden is also good. There are plants everywhere, so you can see enough. Haicang Bridge is the only way from Xiamen to Haicang District of Xiamen Island. The night scene is really beautiful, full of fire and bright lights. There is a fire island below, which is quite interesting, and there are museums and so on. You should buy tickets at the ferry terminal (not at Gulangyu Island, but at Lujiang Road); The Bridge Museum is also good. There are many famous bridges, including Hongkong Bridge and Zhao Zhouqiao, all of which are models. Unfortunately, you are late. There is an ice sculpture carnival, an ice sculpture, the zodiac, a castle, a slide and a track. It can snow and skate. More interestingly, the temperature inside can reach-10 degrees. Haicang Wildlife Park is also good. There are more or less animals in it to prevent bird flu!
