In this four-minute episode of PBS's "History Detectives," Charlotte Brooks, speaks about the relationship between Chinese immigrants and the white populations with which they came into contact in the U.S. Topics covered include the transition from violence to non-violent discrimination, the simultaneous romanticization and distrust of the Chinese, the lack of Chinese legal standing, and the way in which the arrival of Japanese and Filipino immigrants altered the social standing of the Chinese.

Teachers should be aware that the term tong is never defined within the talk. It essentially refers to Chinese organized crime groups within early Chinatowns. The violence and disparity of the anecdotes called to attention in this discussion render it better suited to middle or high school students, rather than an elementary audience.

Brooks holds a BA in Chinese history, as well as a MA and PhD in American history. She currently teaches at Baruch College, and primary academic interests include Asian American history, politics, and community in California.
