Master Ricky Cheung started his apprenticeship with his father at Fuk Hing Lung Mahjong Factory in Kowloon City at the age of 13. As the second-generation owner of the factory, he had over 50 years of experience managing the factory, spanning from 1963 to 2009. From purchasing raw materials from Germany and the local market to manufacturing processes like sawing, polishing, carving, coloring, scraping, packaging and delivery, the factory provided a one-stop service to its customers. It was one of the largest mahjong tile factories in Hong Kong until its closure in 2009.

Master Cheung continued to work until his retirement in 2018. As he does not wish to witness the disappearance of this traditional craftsmanship with the retirement of the previous generation of masters, he continues to collaborate with his daughter, re-presenting hand-carved mahjong in a creative way.
