Dragon water opens the dragon gate. That's right. If the speed is slow, it's ok here. First, the toilet can be installed without any problems. The cashier should sit on the fourth floor and go upstream. This is a choice. Don't rely too much on the entrance wall, or the tiger will be forced to sit still. Mirrors can be placed separately. Don't flush the cashier at the door of the bathroom, otherwise there will be health problems such as high blood pressure. Your sign is water, so I recommend a fish tank.
It's best to put the dragon on the side of 2.
