• Zhao Li argued that his international company had the experience and production pipeline to make a high-quality Three-Body Problem game, while Wang questioned whether it could do the novel justice.
• Qi Hao reflected that the game's mathematical logic mattered more than cinematic presentation, then approached Wang with scratch papers about a coloring problem on directed acyclic graphs.

• Qi Hao judged that current quantitative investing methods in Huaguo were clumsy.

Qi Hao saw that his paper had passed its initial screening and was assigned to an MIT professor for review, though the professor delegated the first look to his busy doctoral student. After tutoring Fang Jiaze, Qi Hao took on three math competition problems for Fang Jiaxue’s friend and began solving them.

• Qi Hao noticed his paper’s submission status had changed to “Editor Assigned” just a week after he submitted it.
