Blowholes are one of the coastal features.
In geology, a blowhole is formed as sea caves grow landwards and upwards into vertical shafts and expose themselves towards the surface , which can result in quite spectacular blasts of water from the top of the blowhole if the geometry of the cave and blowhole and state of the weather are appropriate, but sorry for Tung Lung Island blowhole do not had this feature nowadays.
