The word 'Fuhon' is derived from a historical event 'food and money are the source to enrich people' of "Tokankanki" from encyclopedia "Geimon-ruiju" (a Chinese encyclopedia, literally "Collection of Literature Arranged by Categories").
「富本」というのは、唐代の百科事典『芸文類聚』が引く『東漢観記』の「富民之本在於食貨」（民を富ませる本は食貨に在り）という故事に由来する。
