For Tank Lam Hip-hou, rugby isn't just a sport. It's something that gives meaning to his life.
'If I didn't learn to play rugby,' the 23-year-old says, 'I may have hooked up with gangsters or even become addicted to drugs.'
As a teen, Lam says, he lost his way- and it was rugby that helped him get back on the right track by giving him a purpose.
A migrant from the mainland, Lam came to Hong Kong at the age of 11 and began studying in primary two. 'I didn't like the city,' he recalls. 'I told myself I didn't belong here and I found life in Hong Kong pretty boring. I didn't want to stay.'
After a month, he bought a ticket back home with money from his Lunar New Year red packets. Yet his relatives on the mainland sent the boy back to Hong Kong.
By 2003 he was getting in trouble at school, starting fights with other students. The troubled teen even came to the attention of the police. Yet this would prove to be a blessing in disguise.
