我们知道,接吻是人们用来表达爱的一种方式。在这以前,世界上许多地方的人们却是用接吻这种习俗来表示一种敬意。在非洲许多部落里,土人们有吻酋长走过的土地的习惯。最早吻手和脚是表示对某人的尊敬。在古罗马初期,人们为了表示庄严的欢迎,才吻口和眼。有一位古罗马皇帝准许他最亲近的大臣吻他的嘴唇,次一等的大臣吻他的手,最疏远的大臣只能吻他的脚。 We know that kissing is a way people use to express love. Until then, people in many parts of the world used the habit of kissing to show respect. In many tribes in Africa, the natives have the habit of kissing the land that the chiefs have traveled. The first kiss and foot is to show respect for someone. In ancient Rome, people just to express their solemn welcome, just mouth and eyes. An ancient Roman emperor allowed his closest minister to kiss his lips, the first minister to kiss his hand, and the most distant minister to kiss his feet.
