Living in the hustle bustle in Hong Kong with the world's longest working hours, the creative industry has been developing creative output as relaxation therapy. Meanwhile, they have been signaling the pressing dilemma of their mental health issues due to the public’s lack of appropriate recognition of their value, irregular workload and working hours, and inadequate financial rewards, as they have always been neglected by the society and are not on their own initiatives to change.
