Many women have had the experience of going to the toilet in public places, especially when there are many people. There are few people in the men's toilet, but there is a long queue in the women's toilet. Sometimes they can't wait to rush into the men's room. In order to alleviate this situation, someone invented the female standing urinal. In my opinion, this design is simply anti-human, not to mention inconvenient, uneconomical, unsanitary and inconvenient to use. I wonder if these designers have brains.
