Our usual way of hand flushing is to need a stable "water column", or a large current, or a fine flow, and more to facilitate "low flushing". Therefore, most of the commonly used hand pots and spouts are designed according to the condition of "steady flow". Usually in design, the width and height of the spout will be more balanced.

In the hand punching pot used in Japanese style, the spout is often "narrowed" and "flipped". The function is to "contract" the current into water droplets, while the "flipping" is to facilitate the control of the falling time of "every drop of water". In addition, it is interesting that most of the pots used for Japanese hand flushing are crane-billed pots, while most of the common hand pots that control the speed of water flow are gooseneck pots, which are closely related to the collision point of the current.
