Which direction is best for the head of a wood-carved turtle ornament?

It depends on where you want to place it. If it is at the entrance of the door, your head should be looking into the room. If it is in the living room, your head should not be facing the guests. Turtles are long-lived animals and should not interact with people. For hedging, it is better to look towards the Tai Sui position. If you want to know which place is the Tai Sui position, you can only ask the Feng Shui master. I make mahogany ornaments and don’t know much about Feng Shui. The above is just a personal suggestion
