Shortly after the American Revolutionary War, as the United States had recently begun transpacific maritime trade with Qing, Chinese came into contact with American sailors and merchants at the commercial port of Canton (Guangzhou). There, local individuals heard about opportunities and became curious about America. The main trade route between the United States and China then was between Canton and New England, where the first Chinese arrived via Cape Horn (the only route as the Panama Canal did not exist). These Chinese were mainly merchants, sailors, seamen, and students who wanted to see and acquaint themselves with a strange foreign land they had only heard about. However, their presence was mostly temporary and only a few settled permanently.
