Today I would like to share an ancient village in Cangnan, which has a history of more than 600 years of alum mining and has a resounding name, "the World Alum Capital".
Visiting the site of the mine, they said that the cave could accommodate millions of people, which also showed that the area of the mine had been dug deep by industrious miners who were great working people.
The old street of the village has an ancient Chinese architectural style. The houses are built of stone bricks, which are stronger than wooden houses and are not prone to fire.
