In the absence of weather forecast, how did ancient times predict the weather in advance?

We pay attention to the weather forecast every day, because it determines whether the activities we plan for the next day are smooth or not. In ancient times, technology was not so developed. How do people predict the weather? In fact, there were methods to predict the weather in ancient times.

We often see in TV plays that ancient people like playing the piano very much. Speaking of this, we will first think that people will use it to play beautiful music. We hardly know that strings have another function here. As early as the Han dynasty, the ancients used the principle of abnormal sound of strings to infer the humidity in the air and predict sunny and rainy weather! Because Qin is mostly made of wood, just like there are many wooden products in the houses where ancient people lived. When the weather is abnormal, these wood products will get wet, so people will use it to predict the weather.

Later, people summed up many proverbs according to the solar terms of the year, such as "a knot in one's heart will kill people" and so on. In addition, people will make predictions according to the size of the wind. If the wind is generally strong, it is likely to bring rain or watch clouds. When the sky is dark and accompanied by dark clouds, it is likely to rain soon.

In fact, there are many excellent "meteorologists" in the insect world. Because the senses of animals are many times more sensitive than those of people, working people have long known to predict the weather according to the behavior of animals. For example, fish often spit bubbles out of the water, or birds fly very low and so on. It's all a sign.

In fact, the weather measurement of ancient people is relatively accurate, because these are all experiences summed up from daily life, and even if there are errors, they will not be too bad. So, here I can't help but sigh the wisdom of the ancients. In that era when there was no black technology, I could still predict the weather like us.
