Unlike many Chinese cities, Harbin has a short history. The city is about 110 years old. But it became the biggest city in the northeastern section of China with about 10 million people, and it is the capital of Heilongjiang Province. However, the city has not attracted much foreign investment so the city’s old structures remain. There is a lot of architecture dating from the first few decades of the 20th century when the city was a cosmopolitan city composed of people from dozens of countries. In the 1920s, most of the population was Russian, and many Russian buildings still stand.
