In Chinese, there are aspects of time instead of the past, the present and the future.
过 guò (= suffix): Aspect of Past Experience
过 guò is used to express that someone has done something at least once.
Yet, 过 guò is only used if the action or the experience can be repeated.
Structure: verb + 过 guò.
