Narrated in Chinese, an old professor from Beijing University, at end of Qing dynasty, Republic and early People's Republic of China, tells about what a Ru-ism is doing: follow mass scribes, note strange or fresh bugs and fishes, chant spring wind and autumn moon with head and tail rotating, also explore the reason of country governance peace or war, explore the root to decide mass's living condition, in a light and natural way, touch you softly in tears...北大教授，时值清末，民国，新中国初期，一个儒生，他一辈子在干什么：跟在众文士之后，注虫鱼，吟风月，探索国家治乱之源，生民根本之计。轻松自然，令人唏嘘感叹。
