Rural proverb: two springs a year make hair as expensive as gold. Do you think it's right?

I think this is just a sentence from the countryside. It may be useful in the past, but now it seems that nothing is right. If there are two beginning of spring in a year, the weather will be very cold and even the cotton-padded jacket will be very warm, then the fur of animals will be particularly precious at this time, because the fur of animals is the warmest, and people will definitely go crazy to grab it at this time, so the price will be driven up very high. Why? In spring, fur is as expensive as gold? In other words, people mainly rely on animal fur to keep warm, which is unrealistic now.

In spring, fur is as expensive as gold? We usually only have one beginning of spring every year, so the weather will be more regular. But if there are two beginning of spring in a certain year, it must be very cold. Those cotton-padded jackets we wear in winter don't look warm and can't meet our needs, so animal fur is particularly important at this time. Because people think that the fur of animals can play a good role in keeping out the cold, and it is just right to wear, many animals will be slaughtered and then used to keep out the cold. Once the demand is large, the price will naturally go up and become more and more expensive.

In fact, I think this sentence is not quite right, because in fact, the functions of animal fur and cotton-padded jacket are the same, which does not mean that either one can be strengthened. In the case of very cold weather, their functions are similar, so there should be no mass killing and plundering of animal fur. Moreover, at present, the fur of animals is dirty and there is no good treatment condition in rural areas. If it is used directly after slaughter, it will have a certain health impact.

So I think this sentence is actually incorrect.
