Many actors believe their looks can guarantee them a successful and glamorous film or TV career.
But show business is unpredictable, and many of those involved have realised that continuing education allows them to change professions should they leave the industry.
Astrid Chan Tsz-ching, an actress and programme host at TVB, is one such person. She knows that learning is vital because the entertainment business cannot be relied upon.
'It's changing fast. Our career calls for luck and knowledge. Studying makes me feel more comfortable here and helps me build my self-esteem,' she said.
'The people around me at work are so smart I often feel I'm not clever enough, so I try and compensate by working harder and studying more than others.'
Chan has studied many different courses over the years. When she was pregnant in 2003, she studied for a child play therapy certificate at University of Hong Kong's School of Professional and Continuing Education (HKU Space).
