two couples and four people. Play for three days Mainly look at the sea. How much you spend actually depends on your own choice. It's very different where you live and where you eat. The economic point is to stay in a personal hotel. Caochang Village or Liuzhuang Village in Beidaihe is very close to the sea. It is estimated that the private room is only one hundred a day. They are very polite to others in order to attract business. You can also bargain. But if you don't feel at ease, you can also choose a public hotel near the sea. It's the off-season and it's very cheap. 8 yuan is charged at the seaside except Tiger Stone Park, and everything else is free. Beidaihe pigeon nest park, Jifa sightseeing park and wildlife park are all good. The Great Wall at Jiaoshan Mountain in Shanhaiguan is good. (Note that it is cheap to go to the Great Wall, so don't pay attention to him if he takes you there, and don't pay attention to him if he is a tour guide.) The underwater world of Xin 'ao in Qinhuangdao is good (near the Olympic Stadium), and these are still in operation. Although there are many other scenic spots, they are not in summer and are generally closed. Even if some people go in, they will spend the same money and play a lot less. According to my experience, two thousand yuan is enough for four people, including three days' accommodation and food. It's not easy to earn money. When you go to tourist areas, try to stay in fewer restaurants and buy less souvenirs. When you meet someone who is chasing you to sell necklaces and take photos at the seaside, you must be decisive in rejecting them, otherwise they will be bored to death like flies around you. Hey hey. -It's cool to see the sea.
