張宏道是一位無師自通，卻能表現出恣意絢爛的色彩、構圖協調的素人畫家。他在賣菜閒暇之際用色筆畫出自己的內心世界及生活中的點點滴滴，期能透過繪畫傳遞美的訊息。
Zhang Hong-dao, a common person but a self-taught painter, can express bright colours, coordinated composition. In his spare time after selling vegetable, he draws out what happened or happening in his world, outwards and inwards, hoping to send forth the beautiful messages to everyone.
