The horn shape can make people think of the action of raising arms and shaking arms, which can arouse people's association and convey positive energy. After pouring boiling water, the hot steam comes out from the hole at the top of the ox horn, which has a certain picture sense. The user does not need to take down the cup cover to blow hot water, but can directly blow at one end, and the hot steam will be discharged from the hole at the other end.
