When is October in the lunar calendar?

This year, the second day of the lunar calendar 10 is the beginning of winter solar term. In beginning of winter and China, beginning of winter is regarded as beginning of winter, and China has a vast territory. All winters don't start at the same time except the coastal areas of South China where there is no winter all the year round and the Qinghai-Tibet Plateau where there is no summer in winter. According to the standard of dividing the four seasons by climatology, if the average temperature in the second half of the year falls below 10℃, it is winter, then the statement that "beginning of winter begins in winter" basically conforms to the climate law in Huanghuai area. In the northernmost part of China, the areas north of Mohe and Daxing 'anling have entered the winter in early September, and the capital Beijing has already seen the winter scene in late June 10, while the winter in the Yangtze River basin didn't really start until around the "light snow" solar term.
