Meet Rex Tso, Hong Kong's ring king

Rex Tso Sing-yu may be one of a kind, but like most of us his day starts early and he puts in long hours.

However, his daily grind couldn't be further from the nine-to-five many of us experience - Tso is Hong Kong's only professional boxer and this weekend he steps into the ring for one of the biggest fights of his burgeoning career.

The country he calls home hosts its first ever big-time professional fight this weekend, when Filipino ring phenomenon Manny Pacquiao takes on Mexican-American Brandon Rios for the World Boxing Organisation welterweight title in Macau. Tso, 26, is a starring act on an undercard bristling with up-and-coming Chinese and Asian talent.

Getting to this point has been no cakewalk for the boy from Tuen Mun, whose day starts at 5am with a breakfast of oatmeal and more boiled eggs than any normal human should have to stomach. That's followed by a 90-minute run and a short nap, before he heads to the gym for a four-hour workout.

All this comes as second nature to the young featherweight. Working-class Tso was brought up with the fight game, as his dad was a famous amateur boxer in the 1970s and '80s - the man who has earned the ring moniker "The Wonder Kid" admits the hard days of training can be monotonous.

But the endless workouts are paying dividends; since turning professional two years ago, southpaw (or left-hander) Tso has racked up a record 10 wins - nine by knockout - and zero losses. He has big dreams to become the city's first professional world boxing champion.
