The capital was named White City and for the strengthening of the wall theyperformed construction sacrifices as in the case of the Great Wall of China, or the ancientHungarian castle of Déva in Transylvania. The Huns buried the remains of the people whodied at the site in the wall, tradition holds this is why Helian Bobo’s great wall still stands.
