While at NCCU, Bbrother felt the atmosphere there was stifling and that most of the students had no interest in public affairs, so he and a few classmates formed a group they called the Mountain Guerrillas that would use photography, posters, stickers, street theater, and graffiti to bring up campus issues in a creative way. They aimed to use the "guerrilla" tactic of striking quickly and then scattering.
當時在政大唸書的 Bbrother，有感於學校風氣閉塞，學生普遍不關心公眾事務，於是與同學們組織了一個名為「上山打游擊」的團體，採用攝影、海報、貼紙、行動劇、塗鴉等方式，希望以游擊隊員那種「打了就跑」的靈巧形式，用創作來介入政大的校園議題。
