Shenzhen (深圳; Shēnzhèn in Mandarin, Sāmjan in Cantonese) is a fast- paced city of ambition and enterprise: engineers on the cutting edge of modern technology, hardscrabble farmers coming to the big city in search of a better life, middle managers who dream of someday opening their own factories, designers looking to sell to a global market, and all manner of entrepreneurs from across China.
