YF Drawings began in various forms of quick line sketches contemplating events of the day since June 2015. This is the fifth volume of collections, namely SQUARE THOUGHTs (小生方洞), dated from November 26, 2017 till May 29, 2018。
「小生方洞」是風籽自2015年6月開始的日記式草圖，每次5至10分鐘的繪圖冥想，整理片碎。這是第五集 （26.11.2017 – 29.05.2018）。
