The Begining of Salt Mining
During the Han Dynasty, salt was only known to get from the sea, but then the Han people changed that. They advanced technology by grabbing a drill and digging down. That was known as a Chinese salt mine. They dug down deep enough to get an empty bamboo log and put it into the deep water. They then covered the top of the bamboo up and pulled the bamboo out. They then transferred the water to a bucket or barrel and let the water evaporate. They then had salt!
