Cage maker and repairer is sad that demand for his specialist skills is waning
His face is a study in concentration as he carefully paints the inside of a bird cage.
It has already taken two hours and Chan Lok-choy is not keen on interruptions.
'Sorry, I seldom speak when I am painting a cage, otherwise the paint gets badly distributed,' the 62-year-old says, not taking his eyes off his work. 'I have to work with all my heart.'
But he does pause to examine his work and adjust his large spectacles, necessary these days because of his failing eyesight.
For the craftsman known to the young at the famous Mongkok Bird Garden as Uncle Choy and to the old as Ah Choy, working with cages is not just a labour of love but his life's work.
After all, he has been painting cages for 50 years, starting as an apprentice in his uncle's bird stall in Hong Lok Street Bird Market before it moved to the bird garden in 1997.
