完善社会保障体系

You’ll mostly see this in serious discussions. It’s a favorite of news anchors and people writing academic papers. You use it when you want to sound informed about social issues. For example, if you’re talking about why people are worried about retiring, you might say the government needs to 完善社会保障体系. It shows you understand that the problem is systemic, not just a one-off issue.

This is your go-to phrase for formal meetings, university essays, or when you're watching the evening news with your Chinese host family. If a conversation turns toward the 'big questions'—like aging populations or healthcare costs—dropping this phrase will make you sound like a policy expert. It’s also very common in business contexts when discussing employee benefits on a macro level.

Don't use this for small, personal fixes. If your friend needs a band-aid, don't tell them they need to 完善社会保障体系. That would be like using a sledgehammer to crack a nut. Also, avoid it in very casual settings like a loud bar or while playing video games, unless you're making a joke about how your 'personal' safety net (your bank account) is failing.

In China, the concept of the 'Iron Rice Bowl' (guaranteed lifetime employment) used to be the primary form of social security. As the economy shifted, the country had to build a modern, Western-style social security system from scratch. Because this is a massive, ongoing national project, you’ll hear this phrase constantly in political speeches. It represents the transition from family-based care to a state-supported framework.

You might hear 健全社会保障体系 (jiànquán...), which means to make the system 'sound' or 'robust.' Another one is 构建... (gòujiàn...), meaning to 'construct' or 'build' the system. They all point toward the same goal: making sure nobody falls through the cracks.
