- Mak Sing Yin is 99 years old and has been hand-making tin items such as boxes, mail boxes, buckets, pots and pans from roles of sheet metal for over 80 years. The stump in front of him is well over 100 years old and the metal band around it was made by 'his master' who taught this trade when he was a kid. Mak works 7 days per week and I took this photo on Sunday, 25 Jan 2015. ( 6x6 Fujicolor Pro 400H in poor light )
