Is it better to squat with a trap or a gooseneck?

The squatting pan is equipped with a trap, and its working principle is that there is a water seal at its corner, which can store a certain amount of water, play a role in burping and deodorizing, and prevent the odor of the sewer from flowing back.

If there is no trap, the internal structure of the squatting pan is straight, and the smell is easy to flow back. Setting traps can bring double insurance. It is suggested that when buying squatting pans, you can ask the staff whether there are traps. If you do this, it will still have more functions.

So it's better to stay in the trap.
