Lianyungang, Jiangsu: When drying salt in spring, paint a colorful production scroll

Recently, the salt fields in the coastal areas of Lianyungang, Jiangsu ushered in a busy season, and the salt ponds were dyed with colorful colors.

In Guanxi Salt Field in Lianyungang City, 15,000 acres of salt fields ushered in the peak period of salt-piercing in spring. The sun shines, the silver-white salt fields are like mirrors and picturesque, and the white salt particles are covered with snow, and the sun shines with a crystal luster. The salt workers took advantage of the sunny weather and drove through the machinery and equipment. With the change of temperature and the exposure of sunlight, the water in the salt fields continues to evaporate. Looking down from the air, different concentrations of brine show different colors, and rectangular salt pools seem to be the palette of nature.

Through the process of concentrating, evaporation and crystallization, seawater can be turned into raw salt after several months of drying, and then refined and salt is produced.
