Why do Chinese professionals often work such long hours?

It is 8:40 on a Tuesday evening on the twenty-third floor of a Hangzhou office tower, and Li Meng finished her work two hours ago. The quarterly report has been sent, the tickets closed, the client answered. Yet she remains at her desk, drifting between a spreadsheet and her phone, because fifteen meters away her team lead's coat is still draped over his chair. When he finally stands, stretches, and says "zǒu ba" — let's go — half the floor begins packing up within a minute, as if released by an invisible latch. Nothing in Li's contract describes this ritual. No memo mandates it. But nearly everyone on the floor performs it, and nearly everyone understands why.

In many Chinese workplaces, hours function as a communication system. Staying late says: I am committed to this team, I take my obligations seriously, I can endure. Leaving early — especially before one's manager — says something too, whether the leaver intends it or not. The key concept here is tàidù (态度), "attitude," a category that appears in performance evaluations with a weight that surprises outsiders. Knowledge work is notoriously hard to measure: a product manager's actual output resists simple metrics. So visibility becomes the proxy. Effort must be seen to be counted, and the most legible evidence of effort is physical presence after the official day has ended. Consider Zhang Rui, a software engineer in Shenzhen who left at 6 p.m. sharp for two months while his mother recovered from surgery. Nobody objected. Nobody mentioned it at all — until his year-end review, where his manager described him as technically strong but "not hungry enough." His raise was half what his peers received. No rule was cited, because no rule had been broken. The signal had simply been read. This is not unique to China — every office culture has some version of "face time." What distinguishes the Chinese case is the intensity and the near-universal fluency. Workers do not generally experience the system as deception; they experience it as etiquette, the way one knows not to sit before the eldest at a banquet table.
