Ho Chi Minh City's Chinatown is considered the largest in the world, and covers large parts of district 5 and 6. Cholon was a separate city, 11km from Saigon, until 1931 when both had grown so much they merged into one.
The name of the area fittingly means big market in Vietnamese, Binh Tay Market spills out into the streets around the building, and the whole area is very busy.
All the side alleys and back streets are teeming with manufacturing, recycling and machine workshops and small cafes.
I will update with more posts with images from the backstreets and workshops of Cholon.
