Robert: OK...well, then how much is one jin?
Uranda: Ginseng comes in 6 different grades. It runs from 5,000 to 30,000NT a jin.
Robert: 30,000NT for ginseng?! Do I have to buy a whole jin?
Uranda: You can get a liang if you want. A liang is one-sixteenth of a jin. That would be 330NT.
Robert: Whew! That sounds more like my price range. I'll take two liangs.
Uranda: I'll have my brother cut some for you.

罗　伯：好……那么一斤是多少钱呢？
优兰达：人参有六种等级。一斤的价格从五千到三万都有。
罗　伯：花三万块买人参？！我非得一斤一斤买吗？
优兰达：要的话你也可以论两买。一两是十六分之一斤，也就是三百三。
罗　伯：呼！那听来比较符合我的预算。我买二两。
优兰达：我叫我大哥切给你。
