What are the interesting places in Manchuria?

Manzhouli, located on the Sino-Russian border, is a very clean and beautiful town with distinctive architectural style. It is also a large land port city in China. China Gate and China-Russia Free Trade Zone in the city are the must-see places. Grassland scenery, Mongolian customs, exotic borders and Hulun Lake, the fifth largest freshwater lake in China, are all highlights to attract tourists. To the west of Manzhouli, Guomen is a milky building, 30 meters high and 40 meters wide. Above the national gate, there are seven Chinese characters "China people and China", and not far from the national gate is the Russian national gate. The golden letter "CCCP" inevitably reminds people of the colorful tourism festivals, colorful folk customs, the prosperous Sino-Russian trade zone and the beautiful Russian architecture with distinctive features in the former Soviet Union.
