After Japan lost the war 1945, Japanese painting was soon falling out of favor and replaced by ink-wash painting as the artistic mainstream in Taiwan. Since it was not allowed to teach gouache painting in public, the practice in Taiwan seemed to meet an end while many gouache painters adapt themselves to other media.
When Lin Chih-Chu taught at Taichung Normal School (now National Taichung University of Education) in 1946, he also had to cancel his Japanese Painting Course and replaced it with drawing, watercolor painting, and chromatology. Out of concern for the legacy of gouache painting, Lin decided to start his private classes at home. He selected talented students in each year’s class, provided them with paint and tools, and asked them to come over after school. The teacher and the emerging gouache artists had held several gouache painting exhibitions under the name “Teacher and Student Study Group.”
　The private classes were given a name “Bamboo Hedge Studio,” derived from the bamboo hedge outside Lin’s dorm. Years later, a great amount of students of Bamboo Hedge Studio all became major figures in the founding of Taiwan Glue Color Painting Association and the development of gouache painting in Taiwan.
