Lion is a special animal to Chinese people. A pair of stone lions, a (yang) male and a (yin) female, can often be seen in front of the gates of traditional buildings. The male lion is on the left with his right paw resting on a ball, and the female on the right with her left paw fondling a cub.
The lion was regarded as the king in the animal world so its imagines represented power and prestige. The ball played by the male lion symbolized the unity of the empire, and the cub with the female thriving offspring.
