The so-called earth eggs are neither yes nor no. Earth eggs are actually eggs produced by free-range chickens, which are destined not to be sold in batches, so the whole box with earth eggs written on it is fake. Fixed stalls must be fake, because free-range eggs cannot be supplied stably and the output is limited. The stall has been sold for a long time, at least it is adulterated. Most of the self-produced and self-sold booths are fake. Chicken farmers are very rich. Will they set up a stall for some eggs? At least what is sold for a long time is fake.
Because bad money drives out good money, the sales channels of earth eggs are limited and they can't afford high prices. The key is to rely on your own differences. The place where there are more real goods is online shopping.
As long as you find a good shop, you can buy it for a long time. After all, the difference between earth eggs is easy to tell.
