For a toast:
* 干杯 (gān bēi): This is the most common and direct translation, literally meaning "dry cup." It's used for toasting and is very similar to "cheers" in English.
* 碰杯 (pèng bēi): This means "to clink glasses" and is often used in a more formal setting.
For a general expression of encouragement:
* 加油 (jiā yóu): This means "add oil," which is a metaphor for giving someone extra effort. It's a common way to cheer someone on, similar to "go for it!" or "good luck!"
* 祝好 (zhù hǎo): This means "wish you well," which is a more formal way of saying "cheers" in a friendly context.
The best word to use will depend on the situation.
