In 2015, Catherine organized and founded WAB New Sunshine Student Union in order to help children suffering from leukemia in ward schools. As the founder of the union, she regularly takes team members to visit ward schools (special classroom for children under the treatment of leukemia), plans and prepares activities in advance, selects teaching aids and gifts in person, and warms the hearts of children and parents with music in order to deliver love and beauty of life. Under her leadership, more than 2000 children have benefited since 2015.
