When you and someone else make arrangements to hang out but the plans are not officially made, therefore they can diminish like a cloud in the sky. This is called “cloud plan”.
你和某人安排了要一起出去玩,但没有制定正式的计划,也就是说你们的计划随时都可能像天上的云朵一样随风飘散。这就是“云朵计划”。
来看一下例子:
-So are you and Jo hanging out later?
-I don't know, we made cloud plans.
A:晚点你和乔要一起出去玩吗?
B:不知道耶,我们制定的都是“云朵计划”。
