Beidaihe, Nandaihe and Changli Gold Coast, where is a better place to see the sea?

The main difference between Beidaihe and Nandaihe is to eat and live in Beidaihe and play in Nandaihe. Beidaihe is famous because many national leaders come to sanatoriums to recuperate every summer, and the roads are often closed. It's more prosperous, and there are more hotels and restaurants ~ ~ but there are fewer games, and the beach is not as good as Nandaihe ~ Because there are not many bathing beaches, there are small shell fragments and small stone heads on the beach, so Nandaihe Gold Coast is the best beach in Qinhuangdao. I go to this beach many times every summer ~ ~ You won't regret it if you come to see it ~ ~ In addition, there are many places to play. The most famous place in Qinhuangdao (Nandaihe International Entertainment Center) is here, as well as Haishan Paradise and Xianluo Island. ~ but the living conditions are a little worse. If you eat, there will be seafood stalls by the sea. If you are young and self-driving, these scenic spots I mentioned are very suitable for you. There is also the Happy Ocean Park in Xiale Island, but this is far away, at Shanhaiguan ~ ~ but it's also quite good ~ ~ The tickets for the whole Qinhuangdao scenic spot are not expensive, and the most expensive one is not more than 100 yuan per person. ~ ~ \ I don't know if I'm detailed enough ~ I hope you have a good time ~ ~
