So, what about the heavy snow in Qilian Mountain?

The university in Qilian Mountain happened during the National Day, which was10.5. Heavy snow suddenly fell at high altitude in Qilian County, Qinghai Province. In a short period of time, the national and provincial roads in Qilian County, such as Dadongshuyakou and Jingyangling, entering and leaving Qilian and entering Zhangye, Gansu Province, were seriously covered with snow. In fact, during the National Day, a large number of go on road trip vehicles and tourist vehicles were driving on these roads.
