In "Backstage" and "A Grandmother's Love," Liao captures a moment of concentration in each of his subjects: An opera actor, puffing a cigarette butt, vigorously brushes his stage beard, and a squatting woman intently cleans her granddaughter's ear.
在「後台」與「親情」的作品中，廖心銘不動聲色地抓住了對象全神貫注的一剎那：含著半截香煙的歌仔戲演員正努力地整理他的道具鬍鬚，蹲坐的婦人也聚精會神地清理孫女兒的耳朵，他們都表達了人的「氣」味。
