hanming

To the west of Penglai(蓬萊) , there is a country named Hanming, where people use bird feathers as clothes and quench their thirst with dewdrops. They spend their days climbing high places to fetch water, using stairs made of precious materials like gold, silver, and crystal. Here, there are both icy and hot waters, and those who drink them can live up to a thousand years.
