Kwok-yin suffered from a serious illness when he was a baby. Since then, he has become intellectually handicapped and his right hand cannot stretch due to  muscle disability. After joining The Salvation Army Heng On Integrated Service for Rehabilitation, he developed multiple talents, created many delicate handicraft works and took up different job positions. In recent years, his craftsmanship has been recognised, and he was given a sponsorship by the 'Sustainable Development Fund for Artists', which enables him to launch his own project named 'Kwok-yin Hong Kong Style Clay Skill Enhancement Project' and create more artwork. Every piece of his works reveals his passion, perseverance and potential.
