Worked with JJ in Cheung Sha Wan in the early 90's where he was the Assistant Divisional Commander (Administration). As a newly passed out Inspector, I found JJ to be such a kind and friendly senior officer. A very competent and efficient administrator who kept the division running. He made the job look effortless. I enjoyed listening to his tales and stories in the mess whilst enjoying a beer (San Miguel of course). He was a very popular officer, who was liked and respected by all. One of the officers who made up the rich tapestry of the Royal Hong Kong Police. He will be missed by many. RIP JJ.
