There is a urinal which looks like the kingâ€™s face, and a sink is up on the urinal. Therefore, it seems that the King warns a man who does not wash his hand after his urinating â€œHey!! Wash your hand here.â€ The important thing about this urinal is that we can recycle water. That is, after we wash our hands, we reuse the water to flush the toilet. Therefore, we can save our water. This is the king of urinal.
