A boat, a bamboo cloak, an old man fishing in the cold river-which area is the snow talking about?

Jiang Xue was written in Yongzhou, which is located in southern Hunan and belongs to subtropical monsoon humid climate. The frost-free period is more than 300 days, and the average temperature is 65438 07.8℃. It can be seen that it is rare that there are no birds and no footprints in the mountains. Born and raised in Yongzhou, the author has never seen small water freeze. And there is no fishing in the snow in southern Hunan. There have been many droughts and floods in Yongzhou history, and earthquakes have also been recorded. According to the meteorological conditions around Liu Zongyuan's immortal life, Chronology of Historical Events in Lingling Area (2 1986, 1 version, Hunan People's Publishing House) (2 14- 1 version, BC). The following year, heavy rains caused disasters. "In 808, there was a drought. According to the book Disaster Meteorological Data since the founding of the People's Republic of China, Yongzhou is severely frozen except for frequent droughts and floods. For example, 1969, "The freezing is the strongest since the founding of the People's Republic of China, and the extreme minimum temperature is MINUS 7. 1 degree." 1972 moderate-intensity freezing occurred in early February. ""1974 year of freezing drought "" Strong freezing year 1977. From 1 month to February, due to the frequent invasion of strong cold waves ... more than 6,300 cattle in the whole region were frozen to death, and citrus and trees were seriously lost. ""1early February, 982, a strong freezing occurred, overwhelming a large number of trees, bamboos and telephone poles, causing road collapse, traffic jam, communication interruption and serious losses. " This shows that the climate in Yongzhou is sometimes very cold because of the cold wave. Before and after the Spring Festival in 2003, there were two large-scale snowfalls in the south of the Yangtze River, which affected Fujian and Guangdong. Yongzhou is no exception, even Xiufeng in Guilin is covered with snow. CCTV News Network made a special report. Standing on a high place overlooking the wilderness of Yongzhou, it is white; Standing on the shore, looking at the cold current of num, wisps of white fog filled. We seem to see the snow scene written by Liu Zongyuan. According to Liu Zongyuan's account, there was a heavy snow in Yongzhou in the second year of Yuanhe (807). "Before 67, the servant came to the south, and in the winter of two years, fortunately, the snow crossed the ridge and was in several States in South Vietnam. Dogs in several States are yellow, and people who walk are tired and there is no snow. "(Answer to Wei Zhongli's book" Teacher's Way ") This wonder of nature is probably the trigger and fuse of Jiang Xue's conception.
