There is such a story: the old patriarch led the villagers day and night to transport salt to a certain place to replace it with barley for the winter. One night, they slept in the wilderness with a shining starry sky. The elders still use the method handed down by their ancestors to take out three pieces of salt and throw them into the bonfire, to foretell the changes in the weather in the mountains...Everyone is waiting for the elder’s "weather forecast": if the salt in the fire is heard "cracking" Sound is a sign of good weather; if there is no sound, it means that the weather is about to go bad, and wind and rain will come at any time.
The elder was serious, because the salt block was silent in the fire. He thought it was not good, and advocated to hurry up after dawn. But another young man in the clan believed that "seeing the sky with salt" was a superstition and opposed the hasty departure. In the afternoon of the next day, the weather changed suddenly and the wind and snow were blowing. Only the young people who insisted on leaving late realized the wisdom of the elders. In fact, with today's scientific explanation, the old patriarch is also right. Whether the salt block makes a sound in the fire is related to the humidity in the air. In other words, when the rain is about to come, the humidity is high, and the salt block gets damp, it will be silent when thrown into the fire.
Young people often look down on the old people’s philosophies and one-sidedly think that they are all outdated and useless. In fact, some life concepts are like sea salt, no matter how old it is, it is still a kind of crystallization, and it has the memory of the sea.
