Bi Qi，a common fruit or vegetable， was recorded to be a magical thing which can “melt the copper” in some ancient Chinese medical books. It was introduced to the western countries in late Ming and early Qing Dynasty by Jesuit missionaries. This aroused the curiosities of western people and even was the first mystery to be uncovered when they came to China.From the different attitudes towards “Bi Qi can melt the copper”， we can see that misunderstanding and false communication of culture is more caused by attitude than knowledge.
