一切安好。

You can use it as a standalone sentence. It also works great as a response to a greeting. If someone asks 最近怎么样？ (How have you been?), this is a perfect answer. It feels more polished than just saying 很好. It sounds like you have your life together. Even if your desk is a mess, this phrase says your spirit is calm.

Use it when updating family members who worry about you. It is perfect for the end of an email or a letter. Use it when you want to reassure a friend after a rough patch. It works beautifully in professional settings to signal a project is on track. It is the linguistic equivalent of a warm cup of tea.

Do not use it if things are actually on fire. If you just lost your keys and missed the bus, it sounds sarcastic. Avoid using it in high-energy, chaotic celebrations. It is too calm for a wild birthday party. Don't use it if you want to vent about your problems. It effectively shuts down further questioning about your well-being.

Chinese culture deeply values 'Ping An' (peace and safety). This phrase taps into that ancient desire for a life without turbulence. It reflects a holistic view of happiness. It isn't about winning the lottery. It is about the absence of disaster and the presence of health. It has a slightly literary feel, making you sound thoughtful and grounded.

You might hear 一切都好 in daily conversation. That version is slightly more casual because of the 都. If you want to be extra poetic, try 愿一切安好. This means 'I wish that everything is well.' It is a common way to sign off on heartfelt social media posts.
