Mr Cheung was recently transferred to man the Central Traffic Prosecutions Bureau's hotline and his enthusiasm for life and determination to overcome challenges have greatly impressed his colleagues.

Losing his eyesight after a traffic accident in 1997, Mr Cheung continued to contribute to the Force by serving in Tuen Mun District Police Community Relations Office and Commercial Crime Bureau. His outstanding performance helped him to win last year's Tuen Mun Courteous Officers Award (OffBeat Issue 696).

Speaking about his recent transfer, Mr Cheung told OffBeat he had been assigned to man Central Traffic Prosecutions Bureau's hotline because the post would allow him to further develop his potential.

Mr Cheung said: "Since the new post only requires me to work on one computer system, it makes my life easier. I no longer need to switch my attention from one system to another while handling public enquiries."

The 'challenge fighter' has had to make a tremendous effort to familiarise himself with his duties in the new post. "Like everybody else, I felt a bit nervous about my new job. To overcome that feeling, I spent many nights studying traffic regulations. That was no easy task because I had never worked as a traffic officer before."

Cheung continued: "My colleagues helped me a lot by demonstrating the techniques needed in handling public enquiries and showing me quicker ways to retrieve information. They even saved the regulations onto a floppy disk so that I could study the rules after work on my own computer at home."

Police Constable Cho Wun-tong, who works closely with Mr Cheung, is amazed by Mr Cheung's perseverance. "Mr Cheung is so keen to learn that he even records what we tell him on a recorder. Moreover, he has amazing concentration, a good memory and a very clear mind. That's why he has been able to pick up the job so quickly," Mr Cho elaborated.

Police Constable Kwan Ki-hoi, who also has frequent contact with Mr Cheung, highly praises his toughness and independence. "Immediately after his arrival, I offered him some assistance by leading him to different areas of our office, including the pantry and the wash room. He memorized the routes so quickly that soon he no longer needed my help.

"Working with Mr Cheung is a mutual learning process for everyone of us. We help him to handle job-related problems and he, in return, shows us how to overcome an adversity in life," Mr Kwan noted.
