Will it snow at night in June in Jiuding Mountain, Maoxian County?

If the weather is normal, it won't snow in Jiuding Mountain in June, but there are abnormal times, but they are rare. I saw it once when I just graduated from high school. On June 20th in recent years, the probability of snow is about 10%. But it's true that it's cold at night. Keep warm when you go camping. Stay away from yaks. I won't tell you that I was chased by a yak.
