Where is the fidelity of Russian food in Manzhouli inexpensive?

I have been to two stores. One is a Russian supermarket in the duty-free zone, which is exporting to the national scenic spot. The goods in it are complete and the price is not expensive, and my friends who came back from Russia told me that everything in it is true.

There is also a Russian goods store in my hotel, which is not bad. Xinhe Hotel, located at the intersection of Erdao Street and Suzhong Street, is in the lobby of the hotel. The price is good, it's all real.
