2. It costs 600 yen for admission, and the entrance of the stadium is also a place with a souvenir stamp, just like many scenic spots. We take photos on the bear shaped stone statue. It's so cute. There are 100 yen bear biscuits sold at the scene to feed the bears. The bears are very strong. If you throw biscuits with them, they will stand up, and if you don't give them, they will wave or clap their hands to you. Some will hold their feet with their hands, and they will clap themselves fiercely.
3. There may be no stairs if you go down. For example, if you save on the first floor and then go to the second floor, sometimes you will find that there are no stairs after you smash all the stairs. Otherwise, when you dig deep, there will be no stairs. What's the feeling?

5. Qing and Penglai Weihai have more seafood
when grandparents visit Qing, they are advised to have a look at the coastline of Qing. Bring some food and water when you play. There are rest seats along the coastline
first of all, it is suggested that you set up camp in the hotel near the May 4th Square. Although the cost is a little expensive, it is located in the center of all the scenic spots in Qing, and the transportation is convenient
first, the Naval Museum and underwater world are close to each other. If you want to visit them carefully, it will take you a whole day. Moreover, you can go to underwater world in the morning (there is an aquarium nearby. The ticket price is 30 yuan, which is very beautiful inside). The ticket price is 120 yuan. If you go in as a group, it can be cheaper, 15% or 10% discount; In the afternoon to the Naval Museum, I don't know where you got the news. The ticket price is 50 yuan. 50 yuan is like this, of which 20 yuan is for visiting submarines, and the other 30 yuan is for visiting warships, cannons, helicopters, seaplanes and the Naval Historical and cultural museum. Moreover, the afternoon weather is good. If there is a sunset, the scene is spectacular. If you have time in the evening, go to the trestle to have a play. I personally feel that the impression of the trestle at night is better, and there are few tourists at night. It will be very quiet and listen to the sound of the sea quietly
Second, yesterday's tour may be a little tired, it's cool summer now, so today we can take a sea bath. To the east along the underwater world, there are Lu Xun Park, Zhongshan Park, Zhanshan temple and Badaguan. Of course, these scenic spots are free, and the sea area near these scenic spots is Qing's first bathing beach. You can spend most of the day visiting these scenic spots, then have a cool sea bath when you are tired and relaxed, and then have a cup of Tsingtao beer at the seafood store to make sure you are fresh and cool the next day
three days ago, I had a panoramic view to the west of the May 4th Square, and finally came to the May 4th Square. Maybe you live near here and didn't have a good look around. So let's have a good look this morning. Walking west along the beach of May 4th Square, you will see all kinds of sail style buildings. This is the beauty of "Sailing City". There are music square, various handicraft shops, and large lawns. Listening to music, you can lie on the lawns, playing with accessories or watching acrobatic performances (often performed in May 4th Square), with cool sea breeze blowing, It's very comfortable ~ ~ and then walk east to the Olympic Sailing Center. The huge mast can remind you of the Zheng He fleet. If you don't want to go far in the afternoon, you can go shopping ~ ~ the road behind the May 4th Square is Hong Kong Middle Road, which is the most prosperous street in Qing. There are Carrefour, McKinley, jiashike, sunshine department store and other shopping centers, followed by low, medium and high-end shopping places. If you have enough time, you can take a bus to Taidong commercial pedestrian street, which is the commercial center of Qing, But the air quality is not good, and there are many brand stores. It's nice to have dinner here in the evening
four, if you feel that the underwater world does not satisfy your curiosity, then come to the polar ocean world. Take a bus to the East and tell your brother that the fare to polar ocean world will not exceed 20 yuan. Of course, it's convenient to take the bus. Polar ocean world has penguins from Antarctica, polar bears from the Arctic, wonderful outdoor performances of seals and sea lions, indoor performances of dolphins, and of course, all kinds of dazzling fish from the bottom of the sea. The ticket price is 120 yuan per person, and there is a discount for groups. Then, in the afternoon, you can go to Shilaoren sightseeing park and the world's largest bear ranch. The two scenic spots are next to each other. The ticket price of Shilaoren sightseeing park is 30 yuan, and the ticket price of bear ranch is 120 yuan per person. There are a lot of bears and bear performances here. It's lovely ~ ~ there's nothing to play in the sightseeing park, but it can exercise your judgment and physical strength. There are many ways to go up the mountain. It depends on your choice. In addition, the feeling of climbing is very different. You can read it and face the sea, Five, today you can really appreciate the real charm of the national 4A scenic spot -- Laoshan National Tourist Scenic Spot, but also a famous Taoist mountain and summer resort. The ticket price seems to be 80 yuan per person. I suggest you pack light and enjoy the beautiful scenery in the process of climbing. I've only been to Laoshan once, which makes me very tired ~ ~ ha ha, The spring water in Laoshan is very good. Take a cup and have a try ~ ~ it won't take a day. You may be tired and sweating all over. It's just not far from Laoshan that is Shilaoren international tourist resort Shilaoren bathing beach. The ticket price is 10-20 yuan per person, depending on the situation. The above basically includes all the famous tourist attractions in Qing, and is basically on the same road - Hong Kong Road, which runs from the northeast to the southwest coast of Qing. It is not only a prosperous financial street, commercial street or tourist street, but also a new starting point and high point of Qing, The public transportation system is very developed. After walking this street, you will have a general understanding of Qing, a new city
if you forget to buy a map, you can visit all the scenic spots
