Sao Vang Rubber Factory

Rubber is a transliteration of the word CAAOCHU with CAA being the tree O - CHU is the name of a latex tree of the South American Indians. In the 19th century, after the invention of the sulfur vulcanization method and the successful manufacture of pneumatic tires, rubber was widely used and the rubber industry really developed. Before 1954, there is only a tire repair workshop that belongs to the French at 5 LeThanh Tong street (Boulevard Bobillot). Because of the importance of the rubber industry for daily life, national economy and security, the government decides to build the Sao Vang rubber factory right after the liberation of the North.
Without a rubber factory, we could say that Northern Vietnam’s then newly independent people and the economy would have stopped “shifting”.
