After her father’s passing in 1924, Lee was left to pick up the pieces of her fathers legacy. She soon assumed leadership of the First Chinese Baptist Church in honor of her father, the Chinese Christian Center offered services of free healthcare and English language classes, providing American-Americans a safe space to learn and adapt to the new environment. At the time Chinese people faced hate crimes and violence from other communities.

Lee worked closely with children at her father’s Baptist church in New York City, where she became deeply involved in community service. She helped establish a Sunday school program and was committed to providing education and support for the children in the church. Her efforts aimed to uplift the youth of Chinatown, offering them a safe and nurturing environment. Lee's work with children reflected her dedication to both her faith and the welfare of the community, particularly within the immigrant Chinese-American population.
