Studying in Tiankeng: Days and Nights in the Biology Department of Beiqing

In the Department of Biology of Beiqing University, graduate student Li Ran entered the "Tiankeng" major with a longing for science, but found that the gap between ideal and reality was deeper than the laboratory petri dish. The failure of experiments, competition from peers, the fog of love, and confusion about the future constituted the ups and downs of his studies. From master's degree to doctorate, Li Ran struggled and grew up in the ivory tower of Beiqing, trying to find his own glimmer of light in the "tiankeng". This is a story about youth, ideals and compromise, absurd but true, poignant but warm.
