The origin of rien is when in 712, the first year of Emperor Xuan Zong's reign in the Tang Dynasty, the performers and musicians were gathered together in a garden with pear trees called Rien (pear orchard) at the imperial garden called Seinaien in the north-western suburb of Changan, the capital of Tang, for the purpose of practicing their arts at facilities called Ongaku kyoshu-fu (Music School).
その由来は唐の玄宗(唐)の初年（712年）に、唐都長安西北郊の西内苑内で、芸人達がナシが植えられている梨園と称される庭園に集められ、音楽教習府と呼ばれる施設で芸を磨いたことに始まる。
