维护社会公平正义

You will mostly see this in writing or formal speeches. It acts like a powerful mission statement. You use it as a verb phrase. Usually, a government or an organization is the subject. For example, 'The new law aims to 维护社会公平正义.' It sounds very authoritative. If you use it, people will think you are very well-educated. Or perhaps that you watch a lot of news!

Use this when discussing big social issues. Are you talking about equal access to education? This is your phrase. Are you debating a new legal reform? Drop this in. It is perfect for essays, business presentations, or serious dinner debates. It shows you care about the moral fabric of society. It is the 'superhero' of Chinese social vocabulary.

Do not use this for small, personal gripes. If your roommate eats your leftover dumplings, do not say you are trying to 维护社会公平正义. That is way too dramatic. You will sound like a parody of a news anchor. Also, avoid it in casual flirting or lighthearted small talk. It is too 'heavy' for a first date unless you are both human rights lawyers.

This is a 'hot' phrase in modern China. It is one of the core values promoted by the government. You will see it on red banners in the street. It is part of the national dialogue about development. It reflects a shift from just 'getting rich' to 'being fair.' It is deeply rooted in the idea of a 'harmonious society.'

You can shorten it to just 公平正义 (fairness and justice). You can also use 主持正义 (zhǔchí zhèngyì) which means to preside over justice. Another common one is 伸张正义 (shēnzhāng zhèngyì) which means to uphold or promote justice. But 维护社会公平正义 remains the gold standard for formal contexts.
