[16] Outside of charity and advocacy, the association also assisted in the First World War, canvassing to raise $6000 for a fighter plane representing Malayan women for the British troops.

[22] Tan was among the first to offer scholarships to train more Chinese midwives, who were scarce at the time in the 1900s, lowering the occurrence of maternal deaths in the community.

[23] She donated $5000 towards the building fund for St Andrew’s Mission Hospital, which then primarily served the poorest local women and children, being situated in Chinatown.

[24] Tan was a patron of Singapore Po Leung Kuk, initially an organisation that rescued victims of prostitution.
