Junior 3E student Wan Chi Hou has been working with his teacher Ms. Chan Sio Teng since primary school on a doorbell designed for the hearing impaired.  Over the past four years, Mr. Wan and Ms. Chan have been actively participating in various regional, national and international competitions and exhibitions to share their idea with the public, winning many awards and much recognition. 

After much consultation with Allied Group Limited, both parties signed the technology transfer agreement on June 14, 2022.  The doorbell will be entered into the production line and released into the market.  The idea will be further developed and the doorbell will be produced as a smart doorbell-watch to assist the hearing impaired with their daily lives.

Mr. Wan has been the first secondary school student to enter the international market with his invention.  Follow the link below for an introduction of the smart doorbell-watch:
