This snake is poisonous, with a bright green back. It is called green snake and green bamboo snake in different places. This kind of snake is called green or blue wherever it is called. I found it waiting for prey in the branches of bamboo forests and shrubs, so I should pay more attention to those wild barren hills. When hands and feet are bitten, try to tie them tightly with ropes to prevent blood circulation. After sucking the poison from the wound, it is best to go to a competent health hospital for treatment.
