If you plan a four-day trip, I'll give you some advice ~
Day 1: Suppose you arrive in Harbin in the morning and start walking from the railway station ~ If you see snow sculpture at Sun Island first, you can't see anything at all during the day and night ~ Personally, I think snow sculpture's photography is more northerly.
If you have time, you can also visit Harbin Polar Museum, which is also good, especially suitable for couples or families. You can go to see the world of ice and snow at night ~ there is also a hint, if you use a digital camera to prepare for the cold.
You can check the specific operating procedures online. If you have to live near the central street at night, I suggest you find a small shop, walk more and see more, and some homes can be cleaner ~
The next day: I suggest going to see Sophia Square. After all, it is still a famous building in Harbin. It's also good to take pictures here as a souvenir ~ especially when pigeons take off, it feels better to catch them. At noon, I suggest you go to Lao Dao and browse according to Harbin food map. It will make you eat all day. And many ancient buildings are characterized by careful taste ~ if you are still near the central street at night, you can see the night view of the central street, which feels good ~
Day 3: I suggest you go to Gogol Street. Although it is not a special landscape, it is also a very good choice to take a walk at night. And don't go shopping in the Russian market. Things are bad and dark ~
Day 4: Everyone can consider shopping. If you buy food, which is Lin Qiu's big sausage list, you can consider going to the supermarket. In fact, mountain products is now planted artificially. Just find something clean, delicious and beautifully packaged ~
That's all I can think of at present. I will put forward new ideas and continue to share them with you ~
