Finding something American to sell to the Chinese, whether democracy or widgets, has always been a problem. The first merchant vessel to sail from New York to Canton in 1784 was on a tea-buying voyage, but the cargo it had to exchange was ginseng. American ginseng was consumed by the Chinese for its yin: the female properties of cool, while the native product was thought more yang-heavy. A population explosion may have made it difficult for domestic production to keep up with demand, hence the opening for American ginseng merchants who made a nifty profit.
要找出有哪样东西是由美国销往manbetx3.0 的，无论是民主制度还是零配件，向来就不是件容易事。1784年第一艘由纽约驶往广州的商船就是为了购买茶叶，但它用于交换的货物却是西洋参。manbetx3.0 人吃西洋参是因为其性凉属阴，而本土人参被认为性温，阳气较重。当时manbetx3.0 人口激增，可能使本土产量难以满足需求，这为西洋参商人提供了机遇，让他们赚得盆满钵满。
