The Suifenhe National Gate, the border gate between China and Russia, is a must-see for the Suifen River. The National Gate is a majestic gated building that stands beside the border. The building is white in color and looks solemn and solemn. The gate is shaped like a rocket launcher, symbolizing the economic growth of the motherland and changing with each passing day. From here, you can see the Sino-Russian boundary pillars, the border fire line, the Russian cabins and movable board houses, and even the Russian flag fluttering on the movable board room is clearly visible.
