The next day, you can choose to go to Central Street, or you can choose to go to Sophia Church first. Then go to Central Street (it's near and can be walked). Go to the flood control memorial tower. Then you can choose to go to Sun Island Snow Expo. It is expected to open on the 20th of this month. If you want to eat, I suggest trying a Russian restaurant. I suggest choosing between Huamei and Tados on Central Street. It's all good. I have never been to Huamei, and the price should be a little more expensive than Tados. You can also choose to take a taxi on Friendship Road (the street near the Central Memorial Tower) outside the old road. Personally, I prefer Zhang Fei's steak. Drivers have everything they don't know and it's easy to find. Zhang Baopu is a famous shop. Personally, I think the comments on Harbin's food public comment online are still relatively accurate. Can refer to. There are also some Muslim restaurants. But I know there are delicious places in Changchun, which are similar. It's up to you to eat or not.
If it is only in the city, there is really nothing to recommend. The next day, you can go to Long Ta, the Polar Museum or something. It's not an exciting place, but it's ok.
