               Before a Tulou was built the locals would take the 
              advice of a master of Feng Shui to place the building correctly 
              with relation to the hills, trees and the river. The walls of the Tulou consists of a lower section built from stone 
              blocks held together with  lime or clay with rammed earth walls on top.  The earth 
              used to build a tulou is mixed with sand, silt from the river, egg 
              white and the starch from
              sticky rice soup. The walls are 
              re-enforced with horizontal bamboo sticks. The walls were built 
              inclined toward the centre so gravity pushes them together. 
               The Tulou are three to four storeys high. The bottom two storeys have 
              no outward facing windows as a defensive measure. The thick walls 
              also incorporate escape passages. These 
              homes typically house around 500 people. They are a
              
              UNESCO World Heritage site.  |
