Was the first snake hacked to death by Detective Dee Renjie a real snake?

This is a real snake. At that time, there was no such exquisite synthesis technology, and the cross section was exactly the same as the shadow. Moreover, the chopped snake is a black-browed snake, and all the snakes that appear in front of it are Wang Jin snakes. Wang Jin is fierce. He may be afraid to cut off those black eyebrows that he bought with talent. Basically, snakes that appear at the same time as people are fake, and snakes that appear in close-ups alone are real snakes. I don't advocate or object to killing animals for shooting, but most of the early film and television works didn't have this concept.
