The beginning of winter on November 7 is the first solar term of winter, which means the beginning of cold winter. However, the Qilian Mountains on the Qinghai Tibet Plateau have entered a meteorological winter a few days ago. On the day of the beginning of winter, the photographer photographed the "early" winter plateau in Qilian County, Haibei Tibetan Autonomous Prefecture, Qinghai Province, in the hinterland of the Qilian Mountains. According to the China Meteorological Network, at the beginning of the annual winter solar term, the winter front reaches the central part of North China, the Qinling Mountains and the western Sichuan Plateau. During the beginning of the winter solar term, the process of winter is accelerated, and the winter continues to stride southward. Southern Hebei, southern Shaanxi, Shandong, most of Henan, and northern Jiangsu and Anhui will step into the threshold of winter. As of November 4 this year, most of Northeast China, Xinjiang, Qinghai, Tibet, Inner Mongolia, Gansu and other places have entered the meteorological winter.
