The stone lion, introduced into China in the Han Dynasty, is a common ornament in Chinese traditional architecture. In Chinese culture, lion is regarded as a holy beast. Therefore, Chinese people like to place stone lions in front of the gate to drive away evil spirits. And the placement of the stone lions is quite fixed. According to traditions, the stone lions should be a pair with the male in the left and the female in the right. The appearances of stone lions can be various. As a whole, the lions in the North are simpler while those in the South are more vivid.
