Having graduated with a bachelor's degree, He Zhizhou arrived to report at the emergency department of a tertiary Grade A hospital. Carrying a folding camp bed, he gave off an attitude of loafing and slacking off—arriving late, writing ultra-minimalist medical records, hiding in corners to play games—and was regarded by everyone in the department as a connection hire who sneaked in and as emergency room trash. The head of the emergency department, Zhou Jianguo, was dissatisfied with him in every way, and colleague Chen Lei looked down on and mocked him everywhere; only doctor Fang Xiaowen discovered clues. He Zhizhou, who appeared to be slacking off and lying flat, captured fatal medical risks on the instruments that were easily overlooked with just a passing glance, and even casually guided interns on suturing techniques.
