Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%.
Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.
Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Nanchang is the capital and largest city of Jiangxi Province, People's Republic of China. As of November 2017, the total population in Nanchang City was 5,246,600, while the built-up (or metro) area made of 6 urban districts plus Nanchang county is home to more than 4,300,000 inhabitants. Located in the north-central part of the province and in the hinterland of Poyang Lake Plain, it is bounded on the west by the Jiuling Mountains, and on the east by Poyang Lake. Because of its strategic location connecting the prosperous East and South China, it has become a major railway hub in Southern China in recent decades.
As the Nanchang Uprising in 1927 is distinctively recognized by the ruling Communist Party as "firing the first gunshot against the evil Nationalists", the current government has therefore named the city since 1949 "the City of Heroes", "the place where the People's Liberation Army was born", and the most widely known "place where the military banner of the People's Liberation Army was first raised".
