I am happiest and most relaxed when I climb the mountain with my group friends at night. Mountain climbing can not only eliminate the fatigue of a day, but also bring a good mood and a good sleep at night. Persisting in climbing for three years has obviously improved people's mental state, and it is also a good mood to make friends and relax.

Mountain climbing and exercise are all known to be good things, but long-term persistence really requires perseverance.
