A story tells about an elder villager who led other villagers carrying salt day and night to a town in order to buy food for the winter. One night they camped in an open air with a starry sky above. The elder villager, following the tradition passed down from ancestors, took out three blocks(块) of salt and threw them into the campfire to tell the change of weather in the mountains.
All people waited for the old man's "weather report": if the salt in the fire produced crackling sound(爆裂声), they would have good weather; if no sound was produced, it then meant the good weather would soon end and a storm would come at any moment.
The elder villager looked serious. The salt in the campfire made no sound at all. He urged the whole team to set out immediately. A young man in the group thought it absurdly(荒谬地)superstitious(迷信的) to "forecast the weather by using salt".
It was not until the next afternoon, the weather suddenly changed, with cold winds blowing and a snowstorm coming. In fact, the method used by the elder man could be well explained by modern science: whether or not salt produces sound in campfire depends on air humidity(湿度).That is to say, when a snowstorm approaches, lead to high humidity, the salt blocks will not produce any sound in fire.
Young people often don’t mind the philosophy(哲学) of the old, regarding their ideas as out date and useless. To be honest, however, some beliefs in life are just like salt blocks that are distilled(蒸馏) from the sea: old as they are, they remain crystals(结晶), and carry with them deep memories of the sea.
