A lion cub and a Chinese (joke)

This is a translation of a G+ post

An African lion cub looks depressed. His mom asks him what is wrong.  The cub said: "I have just eaten a person, probably a Chinese". The lioness reprimands the cub "Ate a person withtout checking his passport?!  I told you that the body chemicals of the Chinese exceed standards. How can our bodies tolerate them? The cub's dad consoled: "Don't worry.  The Chinese who can come to Africa to hunt eat and drink what provided by special supply.  This person should be green food.

一只非洲未成年狮忧愁郁闷，它妈妈问怎么了。小狮答道：刚吃了个人，可能是中国人。母狮急了：吃人不看护照！早跟你说了，他们化学元素超标，就我们这身子骨，能扛得住吗？狮爸一旁安慰：别怕，能来非洲打猎的中国人，吃饭喝酒都是特供，此人应该是绿色食品！
