In a public toilet in Wuhan, an internet user spotted an uncomfortable design. He noticed that at the entrance of the toilet, male and female signs were marked "concave" and "convex". The design has attracted widespread attention and controversy.

The user said that such a design is not only inconsistent with the principle of gender equality, but also easy to cause confusion and inconvenience to people who use public toilets. For example, some people who are illiterate or have poor eyesight may not be able to accurately determine which bathroom they should enter because they cannot see the signs.

In addition, such a design is also prone to misunderstanding by people who are not familiar with the toilet environment, and even lead to accidents. If someone strays into a "concave" toilet, it may take a long time to find the right direction, which will affect their itinerary.

For this problem, relevant departments should pay enough attention and take corresponding measures to rectify it. At the same time, public education should also be strengthened to raise everyone's awareness and understanding of gender equality, so as to avoid similar problems from happening again.

Overall, this is a challenge to the progress of social civilization, and we need to work together to create a more inclusive and respectful social environment.
