英文原文:

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.
