Woman: Madam Yan, thank you for the catalogue you sent to us. We have carefully studied it and we are very interested, but a little puzzled, to be honest. Chinese herbal medicine is not really understood outside China. I think that it will take time to introduce your medicine here. However, we think ginseng is well-known. So we would like to have your most favourable offer for ginseng. Especially, we like to know the price for 3-year ginseng in US dollars. We might order a small quantity for a trial.
