As a lawmaker, Chen continued advocating for the rights of the disabled. In addition, Chen repeatedly denounced the use of excessive force by law enforcement personnel. She has attended multiple rallies commemorating the 1959 Tibetan uprising, and supported calls to extend right of residency to Tibetans married to Taiwanese nationals. In 2009, Chen opposed offering insurance to foreign elder caregivers, fearing that domestic caregivers would lose their jobs. She later rejected a 2011 appeal to extend the duration for which foreign caretakers are permitted to stay in Taiwan, favoring changes to legislation standardizing long-term care instead. In 2015, Chen submitted a motion to the Social Welfare and Environmental Hygiene Committee of the Legislative Yuan that would bar rich families from hiring foreign caretakers.
