Their sense of safety is very good, just a “U-shaped” seat is not enough, they also put a pad on the toilet, people will change the pad after use. As we all know, the space of the toilet is limited, the person sitting on it fits tightly to the surface, the air will not circulate when the waste is discharged, the gap design can avoid this situation.

The culture and ideology of each country is different, the toilets used in those countries do not have a U-shaped gap, because Asians are relatively slim and small compared to Americans and Europeans, and so will not feel it is too problematic during the process of using the toilet.
