The macaques that live in the tropical rainforest of Hainan are the smallest in the rhesus macaque species, with a standing height of no more than 50 centimeters.

In the matriarchal macaque society, the alpha male is only titular. The length of his reign is up to the females to decide.

In the Jianfengling Series, CGTN unfolds the amazing biodiversity in the Jianfengling tropical rainforest. Located in China's southern island province of Hainan, Jianfengling Mountains are home to about 80 percent of the flora and fauna species on the island. Fascinating natural phenomena make it a gene bank in the northern rim of the tropics.
