His compassionate nature and exposure to literature prodded in Lin a concern for society's vulnerable that was revealed in his art. In the 1935 work The Remains of the Day, he painted back alleys and dilapidated old buildings that normally wouldn't attract people's notice, using a drab color scheme to depict the life of the poor.
悲憫的天性加上文學薰陶，更驅策林之助將關懷社會弱勢的情感，轉化為筆下世界。1935 年的《餘暉》，他選擇平日不被人注意的狹窄巷道及老舊住屋，以灰暗色系，描繪庶民清貧生活。
