Ms So Kam-mui became paralyzed from the waist down after an accident when she was fifteen. Her misery, however, helped her rediscover the value of life. Through her own sufferings, Ms So deeply feels the hardships and sad plight facing physically disabled people. She decided to use her own life experience to help others, and started volunteering for humanitarian causes. Volunteering has been a part of her life and she has been a volunteer for almost 38 years. Her passion for voluntary humanitarian work is a role model for today's society.

Poverty, disability, and over ten surgeries have not destroyed her fighting spirits. Instead she learnt to value life. Once, a man was in coma after a stroke, and might become a "vegetative patient". Doctors suggested the patient's family stop treatment for the patient. But Ms So encouraged them. She taught them how to tape record encouraging words and Christian psalms and play the recordings for the patient. A miracle happened. The man woke up and could walk without help.

"My time belongs to others. I will do my best to help people. It is because my life is given to me by God," she said. Years on, Ms So takes care of the sick and injured, and provides them with her spiritual support. Regularly she visits hospital patients, including the mentally ill, terminal cancer patients, stroke patients, and the disabled. Among them was a man who was disfigured in a fire. With just a few fingers left, he had difficulties in eating. To help the patient rediscover the meaning of life, she spent time with him and took the initiative to feed him. Her support not only laid on practical help to that patient but also a kind of comfort for him. Influenced by Ms So, he also engages in voluntary humanitarian work today.

Wheelchair bound, Ms So understands how inconvenient being physically handicapped. That motivates her to actively battle for the rights of the disabled. She contacted many government departments and organizations to reflect the lack of barrier-free facilities in Hong Kong and demand them to improve disabled access. She fought tirelessly for public transports to introduce disabled friendly facilities to allow wheelchair access. Last but not least, Ms So appealed to museums in Hong Kong for changing their uneven flooring to give the disabled easy access.
