Which route is better for a self-driving trip from Beijing to Changchun?

If you take the direction of Chengde Chaoyang, there are more mountain roads. If you take the Shenyang direction, there are more buses on the Shenyang Ring Expressway. I suggest you go this way: Beijing-Tangshan-Jinzhou-Fuxin-Siping-Changchun. This way you can avoid the mountain roads and Shenyang.

Geographical location

The center of Beijing is located at 39 degrees 54 minutes 20 seconds north latitude and 116 degrees 25 minutes 29 seconds east longitude.

Located in the northern part of the North China Plain. It is adjacent to the Bohai Bay, the Liaodong Peninsula above, and the Shandong Peninsula below.

Beijing is adjacent to Tianjin and, together with Tianjin, is surrounded by Hebei Province. To the west is the Xishan Mountains, the remnants of the Taihang Mountains, and to the north is the Jundu Mountains of the Yanshan Mountains. The two mountains intersect at Nankou Guangou, forming a semicircular mountain bend that expands to the southeast. People call it the "Beijing Bend". The small plain is the Beijing small plain. As the ancients said: "The land of Youzhou is surrounded by the sea on the left, Taihang on the right, Juyong on the north, and Heji on the south. It is a land of abundance." The average altitude of Beijing is 43.5 meters. The altitude of Beijing plains ranges from 20 to 60 meters, while the mountains generally range from 1,000 to 1,500 meters above sea level.
