决不言弃...

You can use it as a standalone motto. You can also use it to describe someone's character. It often follows a description of a hardship. For example, 'Even though I failed the HSK 5, 我决不言弃.' It sounds strong and determined. It is not something you say lightly while deciding what to eat. Use it for the big stuff.

Use it when you are facing a major challenge. It is perfect for graduation speeches or sports competitions. It works well in a professional setting during a difficult project. Use it when you want to inspire your team. It is also great for personal milestones like marathons or learning a new language. It shows you have 'backbone.'

Do not use it for trivial matters. If you are out of milk, do not say 决不言弃. It will sound strangely dramatic. Avoid it in very casual, joking contexts unless you are being intentionally ironic. It is too heavy for a Friday night party. Also, do not use it if you actually plan on quitting tomorrow. It is a high-stakes expression.

Chinese culture deeply values 'chi ku' (eating bitterness). This phrase reflects that traditional endurance. It is rooted in the idea that persistence is a moral virtue. You will see this phrase on motivational posters in schools. It is the modern equivalent of ancient idioms about grinding iron into needles. It represents the 'marathon' mindset of modern China.

You might hear 永不言弃 (yǒng bù yán qì). This means 'forever never give up.' It is almost identical in meaning. 决不 is slightly more forceful, like a vow. 永不 feels more like a lifelong philosophy. Another similar one is 坚持到底 (jiān chí dào dǐ). That one means 'persist until the very end.'
