Many Poles took part in the construction of this railway line, including Eng. Adam Szydłowski, founder of the Russian Harbin.

The local cuisine is also influenced by Russia. In restaurants, you can order borscht that is not found anywhere in China, and there are bakeries in the city baking bread that is equally exotic to other Chinese (Chinese: 列 巴, lièba).
