Vo Thi Cam Thoa lives with 11 other family members in a house measuring just 15 square meters in the Alley of 245 Nguyen Trai Street in Ma Lang.
Ma Lang is a 6.8-hectare (16.8-acre) area in District 1 bounded by Nguyen Trai, Cong Quynh, Nguyen Cu Trinh, and Tran Dinh Xu streets.
Before 1975 it used to be a cemetery. That changed in 1980-82 when people who had left for new economic zones in rural and mountainous areas returned to the city due to extreme poverty there.
Many of them settled in Ma Lang in makeshift tents and houses.
In the late 1990s and early 2000s the neighborhood became notorious for drugs, and the name Ma Lang became synonymous with some of the most feared gangsters in HCMC.
It now has 530 tenements each measuring less than 20 square meters, which house street vendors, scrap collectors, motorbike taxi drivers, masons, and all types of workers who earn a living by doing manual jobs.
