The weakest snake in China is the bamboo leaf snake. Bamboo leaf green is green all over, moving slowly, with weak toxicity and other obvious characteristics. In fact, different bamboo leaves have different shapes, habits, toxicity and colors, not all of which are green, but also pale yellow, dark green, cyan and sky blue. People usually refer to Fujian bamboo leaves that can't kill people. Bambusa fujianensis is the most widely distributed snake in China, which can be found in all areas south of Henan, and it is also the weakest toxic of all Bambusa fujianensis. Its toxicity test is: hypodermic injection ld5=3.3mg/Kg. In fact, its toxicity is not weak, which is about 3 times that of Agkistrodon acutus. If it is lost, it will be lost in the amount of venom. The detoxification amount of Fujian Zhuyeqing is pitifully low, only about 5 mg, which is less than 5 times that of Agkistrodon acutus.
