Not surprising, one third of the millionaires in China are women and the number is growing ( one child policy). This means that if dad had benefited from the opening up of the Chinese economy the daughter being the only child gets to inherit the business and many dont just inherit but went on to grow the business. The offshoot of women's business success gives rise to a new industry ie provision of female bodyguards . many single successful women prefer female guards to male guards( no employment law in China against sexual discrimination against the male). Daily charge for these female bodyguards who are trained in martial arts is US$300 and the employee I think gets to keep $100 excluding tips.
