The word "don't sit on a tree in summer" has two meanings. The first layer means that it is dangerous not to covet the cool under the tree in summer. There were no fans under the big banyan tree in our village before. Many people like to sit under the banyan tree to enjoy the cool, although some mosquitoes are annoying. But because people often walk under this tree, there are few poisonous insects such as snakes or caterpillars.
However, it is best not to sit under a tree in the wild. One year, I went to a strange village in Henan. At that time, there was no place to rest at noon in summer, so I slept directly under a tree in the corner of a nearby house. I haven't slept for a while and found it a little itchy. When I touched a caterpillar, I looked up. Boy, the wall under the eaves of that house is covered with caterpillars, which makes people feel sick. Later, I learned that there are many caterpillars every summer, and the locals are afraid of being stung by caterpillars and dare not rest under the tree.
The second meaning is related to health preservation. Some people think that summer is very hot, but trees are alive, and the inside of trees contains a lot of water. If you sit under trees in hot summer, these trees will transpiration in the sun, and water and moisture will invade your body, leading to some diseases.
Don't sit on the stone in winter, which is mainly related to health preservation. It's very cold in winter, and the stones are very cold. If we sit on a stone for a long time, our body temperature will make it hot. The cold on the stone will also invade the body, which is not good for the body.
Is it reasonable not to sit on trees in summer and stones in winter? Personally, I still think it makes sense, as can be seen from the examples around me.
As mentioned above, people in our village will enjoy the cool under the big banyan tree in summer, but we usually sit on stools or stones brought by ourselves, and few people will sit directly on the roots.
In summer, stones are not so cold after exposure to the sun, and stones are dead things, unlike trees, which contain water, so sitting on stones is completely different from trees. As for winter, when we are outside in the sun, we usually move a bench, where several people sit and chat, that is, they will sit on a stone, or someone will first put a mat like a cloth on it and then sit on it.
In a word, don't sit on trees in summer and on rocks in winter. This sentence mainly tells us not to do things harmful to our health in different seasons. In the past, the ancients attached great importance to Chinese medicine and thought that the invasion of cold was the cause of many diseases. And in summer, not only people like to enjoy the cool under the trees, but also those harmful insects will endanger people's safety.
