Lee Sai Ho began painting from a young age, and he often features buses in his artwork. Since 2007 he has won various local and overseas painting contests. The Arts with the Disabled Association Hong Kong arranged Sai Ho to learn ink painting and watercolour painting under the guidance of Ms. Liu Tung Mui, Ms. Liu Cheng Mui and Mr. Ko Nam. He also learnt sand painting from Mr. Ma Wing Cheung in 2011.
Sai Ho is aspiring to become a full-time painter, and he is keen on sharing the joy of painting with others, as well as encouraging intellectually impaired individuals to develop their artistic talents.
