Thank you for sharing this interesting story. I have been to Hong Kong once but did not get to explore this facet of the city.
By the way, many thanks for your encouragement shown by you for the artwork produced by Jonathan, my autistic son. Jonathan and I have produced another one and we have mentioned your name.
