In the modern office buildings, the place of the toilet is so private that the staff don’t want to be disturbed when they are answering nature’s call. There is a tendency in China that people are likely to use the squatting type of the toilet , so I design a funny toilet sign which remind people outside that the toilet is occupied now and they should not push the door rudely, also add some fun in our life.
