When did it start to get cold and snowy in Qinghai?

Generally speaking, Xining is cooler in September, so you should put on your coat to prevent colds. It began to snow in Xining after the National Day, usually around the Mid-Autumn Festival, so the heating in Xining is usually turned on the second day after the Mid-Autumn Festival, but even the toilets in the corridor will have indoor heating, so don't worry about whether your existing quilt is thick or thin all year round, but don't go out after the National Day, because it will definitely frost. With a comb, you can know that Xining is the summer capital, and the annual average temperature will not exceed 10 degrees Celsius. As long as the next wiper blows, even in June and July, you should put on your coat and pants to avoid altitude sickness caused by a cold. Therefore, if there is a party, remember not to say that kind of chic (* _ *). It is absolutely necessary to travel to Qinghai Lake. It is best not to wait until the warmest July from May to June, because there are only cormorants left in Qinghai Lake in late June.
