TVB drama, Ups and Downs in the Sea of Love (十萬噸情緣) was produced in 2003 and rebroadcasted in TVB at night lately. Other than 2 mains leads such as Nick Cheung (張家輝) and Maggie Cheung Ho Yee (張可頤), the supporting leads are worth to mention. In 6th episode, Ellesmere Choy (蔡子健) and Maggie were arranged for a matchmaking session and he took advantage of her by touching her back. Hence, Maggie felt mad and slapped Ellesmere who continued to smile and pretended nothing happened.
In 1992, Ellesmere joined TVB acting classes and was arranged to host children show, Flash Flax (閃電傳真機). He was given a title, “tour price” due to participating tour shows frequently. During a program (瘋SHOW快活人) in 2008, Kingdom Yuen (苑瓊丹) exposed one particular TVB actor loved to gain advantage of actresses and was better than Bosco Wong (黃宗澤). Thus, Ellesmere became one of the suspects.
After a year later, Ellesmere worked as a financial consultant after completing the contract with TVB. In 2009 and 2018, he graduated with Business Management degree and doctorate degree. In addition, Ellesmere joined Chubb Life Insurance (安達人壽保險) for nearly 10 years and becomes a branch manager in BOC Group Life Assurance Company Limited (中銀人壽) in 2016.
