From as long as Loke herself can remember, her mother Soon Kui Sim insisted that girls must become literate and having an education. This quality rubbed off on Loke, and for most her life she devoted much of her time to social welfare and education of children especially girls. Yuen Peng remembers her mother had helped two girls from St. Hilda's School in Katong and putting them through university education in Australia. She was President of the Singapore Chinese Ladies' Association, and of the Chinese Women's Athletic Association before the war, and President of the Chinese Relief Fund Ladies' Section in Kuala Lumpur when the Second Sino-Japanese War broke out.
