The salt that the poor people in the village ate was made from saline-alkalized soil. Physician Village was located in the North China Plain. Due to the drought, the fields were filled with saline-alkalized soil! The salt that the poor ate came from the saline-alkalized soil. They scooped up the saltpeter soil in the saline-alkalized soil and put it in a basket. They poured water from the top and connected a basin to the bottom of the basket. They let the water that had seeped through the saline-alkalized soil drip into the basin and let the water evaporate under the sun. The remaining white crystals were salt. People used this salt to marinate pickles. The salt was composed of nitrates and was highly toxic. However, the poor had no choice. They knew that they were going to die, so they had no choice but to do so.
Almost every family had two large vats in their yard. The water in the vats was never changed, only added with salt. The vats were always marinated with cabbage, watermelon skin, old cucumbers, carrots, white radishes, cowpeas, and other vegetables. The salt in the vats was very heavy. Under the sun, a layer of salt would be frozen on the surface of the vats.
Sometimes, when we were so hungry that we couldn't find anything to eat, my brother and I would pick up a piece of salted vegetable in the jar to eat to satisfy our hunger. Who knew that eating salted vegetables on an empty stomach would make our hearts burn even more uncomfortable.
