First of all, during the production and transportation of the goblet, due to some uncontrollable factors, such as the vibration during the production and transportation, the goblet itself may have some minor defects. When subjected to external force, these defects may cause the goblet to break. For example, some small flaws in the production of the goblet, or excessive vibration during transportation, may cause the goblet to break when eating.
In addition, if the goblet is broken when eating, it may be due to improper use. For example, if the goblet is excessively heated or cooled, or used to hold some corrosive liquids, it may cause the goblet to break.
Therefore, the breakage of the goblet during eating may be just an accident, which has no special predictive significance. From a practical point of view, we should pay attention to safety when using the goblet to avoid the goblet from being broken.
