San Francisco Overseas Chinese Leader: Transoceanic Intelligence Line

In 1941, patriotic overseas Chinese in San Francisco, USA, were proficient in Chinese, English, and Cantonese. They were engaged in Chinese import and export trade, and established a transnational intelligence line from the United States to China to deliver information about the Pacific War to the country. At the same time, they lobbied overseas Chinese and civilian forces in the United States to obtain arms and material assistance to fight against Japanese spies stationed in the United States.
