People in Alley 84, Bui Vien Street, District 1, begin setting up shops to begin trading at 5 p.m.
The 500-m alley is home to hundreds of families who have migrated from various places.
The vast majority of the people are seniors who must work to support themselves, while some get government support or have children or grandchildren taking care of them.
Bui Vien, De Tham, Do Quang Dau, and Pham Ngu Lao streets have for long been dubbed backpacker streets because they attract a large number of foreigners, especially in the evenings when bars and clubs remain open until late at night. In contrast, the alleys behind them are lined with tiny houses built before 1975.
