Ly Hoang Long is a Vietnamese photographer based in Dalat city in southern Vietnam. Here is an overview of his photographic work with explanations on the tea culture in Cau Dat in Dalat region located at 1500m altitude .
The first tea factory was built in Cau Dat in 1927 by the French colonizers . Tea culture existed before that date but production was only open to local needs. Currently Cau Dat is one of the main areas which supplies tea to South Vietnam mainly green tea.

A special feature in the technique of picking : gatherers fix razor blades to the index to facilitate the removal of leaves.
This photo clearly shows the blade ready to cut the stem of the tea plant.

A big thank you to Ly Hoang Long for sharing his work. You can view all of his photos around the tea Dalat to this address.
