Fujian Tulou The Earth Tower Of Hakka Has A Long History. As Early As One Thousand Years Ago, Some Of The Original Hakka Migrated And Settled At The Sparse Yongding Area. In Order To Protect Themselves Against Bandits And Wild Beasts, They Used Local Materials To Build Tall, Multi-storey Circular Earthen Buildings Where A Whole Family Or Clan Could Live In. These Are The Earth Towers That We See Today. Photo
