On Nov. 30, the Hangzhou Safari Parkheld a 100-day birthday celebration for the South China Tiger triplets named Ao Ao, Li Li, and Gei Gei.

They are now all in good health , with each weighing between three and four kgs.

The keepers decorated the room with birthday balloons, streamers, small toys and other materials for the three little creatures.

The South China tiger is listed as one of China's ten most endangered animals, with even rarer populationsthan the panda. Due to the genetics of the South China Tiger, reproduction is difficult, and tripletsare even rare.

In recent years, Hangzhou Safari Parkhas been studying on the breeding technology of South China tiger. Since the first one introduced in 2014, a total of 12 South China tigers have been born here.
