Tang says his designs are inspired by inscects such as bees, cicadas and butterflies. The competition is part of CHIC '99, China's biggest fashion event of the year. Chinese textile officials have pushed hard to move China away from the design-poor environment where clothing designed by foreign producers was manufactured for overseas markets, towards the goal of producing top-class designs of their own.
