Do Ngoc Ha is a single mother who drives for a ride‑hailing service. In 2017 she started the Hoa Tu Tam charity kitchen, and for nine years she and her family cook 300‑400 free meals every Sunday for oncology patients and their families in Ho Chi Minh City.

The idea started when Ha gave a half‑eaten loaf and water to a hungry child under Nguyen Van Cu Bridge. Seeing the child's need made her decide to cook meals for homeless people, and later for hospital patients.

Today the Hoa Tu Tam kitchen has 45 members, including 15 core volunteers. It works six days each month – four Sundays and the 1st and 15th of the lunar calendar – and prepares 500‑800 vegetarian meals on those two days. On Sundays the team also makes 300‑400 non‑vegetarian meals for oncology patients and their relatives.

Most of the food, even meat and fish, is given for free by benefactors and suppliers, so the meals cost nothing for families. Ha’s story shows how one person’s kindness can create a strong community that helps many people and saves money.
