What is the "war situation" at the scene where the weasel bites the green snake?

The scene was very intense and lasted for more than 20 minutes. On September 7, 2020, some residents found a weasel and a green snake biting each other in their own community. Judging from the situation, the green snake is obviously at a disadvantage. After playing for more than 20 minutes, the weasel got impatient and left by himself. Green snake saw the weasel leave and wanted to leave, but was caught by the property called by the residents.

The weasel, also known as the weasel, is a carnivorous animal with khaki fur. It likes to eat all kinds of mice and rabbits. Everyone knows that rabbits are alert and run fast. Once, my family and I came back from the Qingming Festival to worship our ancestors and met a hare on the mountain. Several adults chased around the mountain for a long time but failed to catch up. Finally, it was run away by the hare. It can be seen that rabbits run very fast, and weasels can also prey on rabbits, so weasels are not vegetarians. Although it looks silly, it is very effective. Not only can you catch rabbits, but you can also gain the upper hand in the fierce battle with green snakes. Although its body is small, it has great courage and strength.

Green snake also has an elegant name among the people, called Xiaoqinglong, which often appears in the south of China. It is not the kind of snake that will actively attack people. It won't bite you unless you provoke it. It is also because of this feature that I think it is very likely that the weasel provoked the green snake before it fought back.

Green snake is different from bamboo leaf green, which is poisonous, while green snake is nontoxic. Everyone must distinguish clearly. If you meet Zhu in the wild, run quickly. If you meet a green snake, don't provoke it and walk away by yourself. The most obvious feature that distinguishes green snakes from bamboo leaves is their eyes. This green snake is black and has big eyes. Bamboo leaves are triangular with small eyes, just like villains with triangular eyes and decent people with innocent big eyes in TV dramas, so we can distinguish them.
