Those places are necessary for traveling to Daxinganling area.

The first stop is Jiagedaqi, which is the administrative office of Daxinganling region. Even if you arrive at Daxinganling from south to north, there are no special attractions, but they are symbolic. You can buy specialties, pine nuts and mushrooms here when you leave.

The second stop, Mohe, to be honest, nine times out of ten, the trip to Daxinganling was directed at Mohe. The northernmost part of China is very attractive. You can experience the feeling of extreme sunlight in summer, and enjoy the excitement brought by snow and ice at MINUS 30 degrees in winter, which is the best choice for winter travel. Specific attractions include: the northernmost one, the northernmost latitude and longitude landmark, the scenic spots along the Heilongjiang River, the Arctic Post Station, the rouge ditch (Jingou), and of course, seasonal attractions. The motherland on this side of Heilongjiang and the homeland on the other side of the river are now Russian houses (visible to the naked eye, across the river), so remember.

The third stop, Manzhouli and Hulunbeier (Hailar), if divided according to pure geographical boundaries, these two places are out of the geographical category, but I highly recommend going, especially Manzhouli (the largest port, gate and border pillar between China and Russia), which is a transition zone from forest belt to grassland and one of the best grasslands in the world. Here, you can experience the customs of Mongolia, Russia and other ethnic minorities, and you can also go to Mongolian yurts to eat mutton.
