Whakaotihia te rerenga e whai ake nei: Ko Liu Bingzhong (; 1216<unk>1274), ko Liu Kan () he kaitohutohu a Yuan dynasty me te kaihoahoa. I whanau ia i Ruizhou (Rui prefecture), i te wa o te Jin dynasty. I te tau 1233, ka uru ia ki te tari tari a Jin. He rangatira tonu ia i muri i te wikitoria a te Emepaea Mongol i te Jin whai muri i te
Mongol<unk>Jin wars, engari i muri mai ka noho ia hei tohunga. Heoi i whakaaro tana kaiako kia kaua e tanumia tana taranata, no reira i taunaki ia i a Liu Bingzhong ki a Kublai Khan, kia noho hei kaitohutohu mana. I tenei wa, i whakamoemititia ia ko te "E rima nga Taonga i Xintai". I whakawhiwhia ki a ia nga mana ngaro i ahei ai ia ki te tohu i te heke mai me te awhina i nga mahi hoia. He nui te awe o Liu ki nga hoahoa taone o te wa o Yuan, a e mohiotia ana kua whakamaherehia e ia te taone nui o Yuan o Dadu me tona taone nui raumati o Xanadu (Shangdu).
