What is a donkey friend?

Both "donkey friend" and "mountain friend" are domestic names for outdoor sports lovers. "Lv You" refers to people who take part in self-help tours, general explorations, mountain climbing and crossing, and comes from the homonym of "Lv You" and "Lv You". "Mountain friends" refer to mountain climbers and rock climbers. In recent two years, a new term "colored donkey" has been derived, whether it is a photographer or an outdoor sports enthusiast.
