This kind of expression helps humanize the otherwise distance created between the Chinese development world and the otherwise Western portrayal.
A few thoughts from my experience living in China. When living in China, I didn't see any appeal in the overworking culture.
Most developers with families worked normal hours. People who were single made time to spend time with friends. I didn't see the overwork ethic it in a positive light at all. Keeping in mind normal developers salaries in tier 1 cities for China is sub-1k USD a month. In tier 2 cities, I can only imagine it gets exponentially lower and so forth for smaller cities.
