What did America learn from the Opium War?

We are talking about the Opium War in my Chinese history class, and my professor mentioned something very interesting last class about phrases adopted by Westerners during this time period. The two that come to mind are "long time, no see" and "take a look see." Before the start of the Opium War China was actively trading with the British and (after the end of the British East India Company's monopoly on Chinese trade) the Americans among others. Western and Eastern traders used translators out of necessity, but there were certain phrases that became widely known by the Western traders and even brought back to their prospective countries. For example "long time, no see" does not really make sense as an English sentence, the syntax is all wrong. BUT if you consider the Chinese phrase "hao jiu bu jian" and you translate it quite literally what do you get? "Give me fried dumplings!" No, I lied. Actually the direct translation is "long time, no see." Ta da!!!
