Did people in medieval times have a stronger sense of right and wrong? It is a controversial question, but Kwun Tong Junior Police Call member Choi King-hong will certainly say 'yes'.
He puts his adoration for ancient chivalry into artwork.
'People in the older days were more simple and honest, compared with the modern prevalence of lusting after material things,' said the 19-year-old toy designer, who joined JPC three years ago.
His pictures include a magnificent warrior riding a tame dinosaur instead of a robust horse as knights of old would have managed.
'I admire youngsters in medieval times. They were more aware of loving their countries,' he said.
The warrior in his picture is using a sword to smash the Chinese character for crime. King-hong says it should remind modern teenagers not to break laws and understand the spirit and nobility of the medieval knights.
