I want to go to Qinhuangdao for three days during the National Day, can you recommend a suitable itinerary for students?

It is recommended to spend a day in Shanhaiguan and Laolongtou scenic spots. In addition to visiting the Great Wall of Shanhaiguan, you can also go to Ledao Ocean Kingdom. <br/>Play a day in Beidaihe, go to Pigeon Nest Park to watch the sunrise. <br/>Play a day in Qinhuangdao City, go to Xin'ao Underwater World, where Qinhuang begged for immortals to enter the sea, and take a cruise ship on the Princess.
