2. There is actually a difference between beginners' ski slopes. 5 degrees and 40 degrees can be greenways. There are obvious differences between large professional ski resorts and snow trails. The better the ski resort, the more difficult it is. The blue slope of the world's top ski resorts is higher than that of ordinary ski resorts, and the double black diamond ski resorts are also difficult.
3. The simplest snow trail is the green snow trail, with gentle slope and white snow surface, which is very suitable for training. The snow trail slightly higher than the greenway is blue. The blue ski trail is suitable for the skiing level after one week, and the difficulty has increased to a certain extent. The red snow trail is suitable for intermediate or advanced skiers, and there will be some light snow slopes on the snow trail, which requires high technology.
