`加油` is used in countless situations, from the most public spectacles to the most private conversations.
At Sporting Events: This is the most classic usage. Entire stadiums will chant “加油! 加油!” to encourage their team.
For Exams & Academics: Before a major exam like the `高考 (gāokǎo)` (college entrance exam), you will see “加油” banners hung on school gates. Parents, teachers, and friends will all say `加油` to the students.
In the Workplace: A manager might say it to their team before a major project deadline: “我们一起加油!” (Wǒmen yīqǐ jiāyóu!) - “Let's all work hard together!”
Personal Encouragement: If a friend is sick, feeling depressed, or tackling a difficult personal goal (like quitting smoking), `加油` is the perfect way to say “Hang in there, you've got this.”
On Social Media: It's a very common comment on posts where someone shares an achievement or a struggle. It's often accompanied by the 💪 emoji.
Literal Meaning: Don't forget the original meaning! You use it when you are literally getting gas for a car or other vehicle.
