Is there any avanti in history?

There is no such thing as two generations of love in history. Two generations of love is a typical figure in Uygur legends. "Two generations of love" means that a teacher, a knowledgeable person, is a title, not a name. His name is Nasreddin. In order to show respect for him, everyone also called him Hoga Nasreddin Erjiqing (Hoga is also a title, meaning "teacher").
