The tiger-spotted snake
is an exaggerated legend.
There is also a legend that it is a cockscomb snake, which stands ten feet high.
This kind of snake is widely distributed in China, and it is probably what you see.
It's impossible to have antlers. It's possible that it just ate something
and hasn't swallowed it yet, and you just saw it.
Maybe it's just a mouse's foot (I haven't raised it, and I don't know if it can eat mice
), because snakes swallow everything from scratch, and finally there are two
feet left, one on each side. You were scared and ran away at a glance.
