Generally, feng shui turtles are raised, but turtles are spiritual, and raising them is better than eating them. The main functions of common turtle culture are:

1. Keeping turtles can ward off evil spirits.

2. Use tortoise shells to block evil spirits.

3. Strengthen the movement of fire, drive away evil spirits, and prevent people from falling.

4. Improve the air quality at home.

Turtles walking around the house basically don't need to be fed, because they suck microorganisms in the air, so turtles have a long life. Keeping a turtle at home and letting it suck microbes is also one of the ways to improve home feng shui.
