There is water, it is smart, there is water, it is quiet, it is combined with movement and static, and the lively atmosphere is beautiful. So there must be a water scene in the courtyard. When people see the water, they are always very excited and happy, no matter if they are adults. Still children will have the same emotions.
Perhaps this is the charm of yard fountain gate. Different ways of water flow give you a different visual experience. Whether it is a modern landscape or a classical garden, there are a lot of water features.
