BackgroundChu Lam Yiu was 27 when she founded her flavorings and fragrance business. Since renamed Huabao International Holdings, the company makes tobacco flavorings for China's top cigarette makers. It also produces fragrances and food flavorings for use in detergents, beverages, dairy products and cosmetics. In 2006, Ms Chu took her company public through a reverse takeover -- a financial transaction that avoids the conventional procedures of filing prospectuses and undertaking Initial Public Offerings (IPO)..
