What does it mean that someone outside Yanmenguan wears fur coats in the morning, wool in the afternoon and eats watermelon with a stove?

Poetry is written in Turpan. Describe the weather outside Yanmenguan changes greatly, and the temperature difference between morning and evening is large. Xinjiang is rich in melon and fruit resources. Eating melons and fruits in summer is not only common, but also eating watermelons in cold weather is rare. Melon farmers in the north and south of Tianshan Mountain have melon pits, which are good at storing fruits and vegetables. Generally, melons and grapes are hung in melon pits, and watermelons are buried in grain piles or sand to keep fresh. The most interesting thing is the way farmers in southern Xinjiang store grapes. 9.5438 June+10 When the grapes ripened, they were hung in a specially-built earthen house. This house is not too high, the walls are particularly thick, the doors and windows are small, and it is easy to keep warm. Then close the doors and windows, raise the loess and let it fall on the grapes to form an insulation layer. In winter, they put a bowl of water on the windowsill to measure the temperature inside the house. If there is a thin layer of ice in the bowl, it means that the temperature in the room has reached below zero. If the ice is thick; This means that it needs heating. The heating method is to bring a sheep in and raise it, and use the heat emitted by the body to adjust the temperature in the house, so as to achieve the purpose of antifreeze and grape preservation.

In the dead of winter in Xinjiang, people can see people eating watermelons or melons on the streets covered with many city towels with falling snowflakes around the brazier, which is probably rare in other parts of the country. But in winter, Uighur hometown will take out watermelons and melons from the melon pit after dinner, set up a tin stove to invite everyone to eat melons, and let guests appreciate the customs of Xinjiang.
