But it's not a matter of knowing all the conventions and rituals in different cultures. It's impossible to collect all the information you might need to be relaxed in the many different cultures around the world. Sometimes all that's needed is tolerance if things might be different, and awareness you're your behavior in your own culture may not be suitable in another.
但是这不等于说我们需要悉数掌握不同文化的风俗习惯和礼仪。你不可能掌握全部必备的知识。有时候，当情况有所不同时，你所需要的仅仅是宽容，并且要意识到，适合你自己文化的行为举止未必在另一种文化中也行得通。
