A Mangshan expert continues his work with the viper that made him famous, Xing Yi reports.

He was the first to discover the Mangshan pit viper, an endangered venomous snake, and have it recognized as a unique species. He has been bitten nine times by the snakes, surviving each encounter but losing a finger after the last bite. Some people also call him "Dr Snake".

He is Chen Yuanhui, a grassroots expert on poisonous snakes.
