1. Observe the color and texture of the snake whip. The real snake whip is usually pale yellow or grayish yellow, with a certain luster on the surface, soft and tough texture and certain elasticity. Fake snake whips generally present bright colors, lack luster on the surface, and are hard or too soft in texture, without the soft and tough texture of real snake whips.

2. Observe the shape and structure of the snake whip. A real snake whip usually presents a slender and slightly curved shape. There are many tiny scales on the whip body, and there are obvious serrated protrusions on the edge of the scales. False snake whip usually presents a relatively short shape, with a smooth surface and no scale-like structure of real snake whip.

3. Observe the source and packaging of snake whip. The real snake whip usually comes from snakes that have been professionally raised and have a good ecological environment. The package will indicate the detailed information of the product, including the manufacturer, production date, shelf life and so on. The fake snake whip may come from snakes of unknown origin or obtained by illegal means, and the necessary information may be missing or untrue on the packaging.
