Sophia church is in the lower right corner of the map, and on the left is Central Street (the longest pedestrian street in Asia), about 500 meters away. In Sophia Cathedral, next to Maikaile Shopping Center and Harbin New 100, you can find it with the naked eye near Sophia, because Sophia and these two big shopping malls are nearby, so you can go shopping. In the central street, there are big shopping malls in Song Lei and Jin 'an. You can also go for a stroll (there is a Haagen-Dazs home in Jinan right at the door. Song Lei has a Starbucks, which is also at the door. There is also a golden sun on the central street. There are many people in it, but everything is very cheap. I've only been there once to join in the fun. There are many shops on the central street. You can go in and have a look if you are bored. The specialty you can buy in Central Street is Russian goods, especially dolls. There are quite a few tourists who buy this thing, and then there is Harbin sausage (you can buy it on Central Street, I forget the specific location. You need to ask yourself. You walk from Sofia to the central street, not far from the store. This is really great. I personally like to eat children's sausages (lean meat). If you have two kinds of snacks in Central Street, don't miss Mattel Popsicle and Mattel Bread. I think popsicles are ordinary, but bread is delicious. What's more, why don't you go to Golden Sun Shopping Mall when you say you want to buy something with high cost performance? Many things are very cheap. I can't answer what you said (3). The fast food restaurant on Central Street seems to have many specialties. I really didn't notice, but you can consider going to MacKay for a buffet at noon. It used to be 180/ person. You said (4), you can go to Sun Island by yourself. When you walk to the north end of Central Street, there is an underground passage. When you walk through the underground passage, you can see the Flood Control Memorial Tower, one of the landmark buildings in Harbin (there are two buildings in the middle, the first one on the left is Parkson Shopping Center, which is cheaper than other shopping malls, and the second one is Wanda International Studios, you know. If you have enough time, you can go to Parkson or Wanda to watch movies. I saw Superman's steel body IMAX the other day. When you get to the Flood Control Memorial Tower, you can see the Songhua River by the Songhua River. When you look to the left, you can see the cable car. Cable car is a way to transport people to Sun Island. The second way is that you will be accosted by an aunt on the river and ask if you want to take a boat. You can also tell her that you want to go to Sun Island by boat (like 10 yuan). By the river, there are two ways to reach Sun Island. If you go to Sun Island by boat (cable car), you should go to the scenic spot first (there is no charge for the scenic spot). Follow the crowd and you will find the side door of the scenic spot in Sun Island. Ok, buy a ticket. There are two ways to visit Sun Island. First, you can visit it yourself (I personally don't recommend it. Sun Island is quite big. If you go for the first time, you won't find many things and you will have to take many detours). If you visit by yourself, it may take about 1 day to complete the tour. Second, be a sightseeing bus (for example, 30 yuan, sightseeing bus will stop at a scenic spot, and then you will go down and wait for you to see the scenic spot before going to the site in sightseeing bus, that is, the parking place, and you can get on the bus and continue to visit when the bus arrives). This way is better, you can go to the place you want to see for a while, without wasting time and detours. It takes three hours to walk (if I remember correctly, the focus of sightseeing seems to be the main entrance, where you can take pictures, but you'd better ask the driver where his destination is and which stop is the main entrance). If the midpoint of sightseeing bus is the main entrance, you have to take a taxi (it is difficult to take a taxi at the main entrance of Sun Island) or take a bus. If you take a taxi, you just need to take a taxi to the highway bridge. Where is the big bus stop on the highway bridge? You can take Line 74 to the Flood Control Memorial Tower, get off at the Flood Control Memorial Tower Station and walk about 100 meters to the north end of Central Street. If you choose the main entrance exit of Sun Island, you can look for it at the main entrance. I remember clearly that there was an overpass there. You have to cross the overpass to wait at the bus stop sign across the street (if you can't find it). All buses go to the highway bridge. You can ask the bus stop on the highway bridge when you get off. Get off at the bus stop 100 meters away from the highway bridge, and then you can take bus No.74 or do it at another stop. It takes four hours from Sun Island to Central Street, maybe a little more. That should be enough time. Playing by hand is still very tiring. I hope I can help you (there are too many people on the central street in the middle of the night, handsome guys and beautiful women, short skirts and stockings, haha, you know. In the Flood Control Memorial Tower, facing the Songhua River, walk along the river bank path on the right hand side, and you can reach the snack street outside the road in about 30 minutes. There are many people there, and there is a shemale show in the evening ... and the food is quite good)
