What is the old salt of old salt lemonade?

The old salt of lemonade is the salt of Danzhou Millennium ancient salt field. Millennium ancient Yantian is located in Yantian Village, Yangpu Peninsula, Hainan, and has been approved as a tourist attraction. According to the characteristics of high temperature and scorching sun in Hainan Island, salt workers changed the method of "cooking seawater as salt" in the past. They poured Shanghai water with sun-dried sand, filtered it to make brine with high salt content, then poured the brine into a stone trough and exposed it to the sun to make salt.

Because the salt here is delicious and has curative effects on many diseases, after Emperor Qingganlong heard the newspaper, the imperial book "Zhengde" was given to Yantian people. Hainan Millennium ancient salt field is known as the earliest salt-making field with sun exposure, which completely preserves the original folk salt-making technology. There are more than 1000 inkstone salt troughs with different shapes, which are densely covered with beaches. There are still more than 30 salt workers in Yantian Village, who work in this Yantian every day in the ancient way of 1200 years.
