Peter Yung Wai-chuen's first documentary One Day in Locke (1971) was made to fulfil the wish of his teacher-mentor James Wong Howe, capturing the first Chinatown in the US. Locke locals were Chinese labourers who had come in the 19th century to build the railroad in California. As time passed, the town slipped into a slow decline which shrouded it in poetic desolation.
