By Donny Kwok HONG KONG (Reuters) - A year after China ordered public officials off the fairways in a crackdown on graft, the business of golf is betting hunger for the game among middle class fans and an Olympic medal for a home-grown star can drive the sport back to growth. The PGA Tour, organizer of golf's flagship events, says it wants to more than double the number of events on the Chinese mainland as Beijing basks in the glow of a bronze medal in Rio for Feng Shanshan - also a multi-millionaire winner on the international Ladies PGA Tour. Meanwhile Honma Golf Ltd, maker of the world's most expensive clubs, makes its debut on the Hong Kong stock exchange on Thursday after a HK$1.26 billion ($162 million) listing, touting the chance of China growth as a key attraction in its prospectus.
