In our communication, we need to respect everyone's identity and occupation. Therefore, it is suggested to use formal addresses for female college students, such as "classmate", "college student", "senior sister" and "junior sister", so as to respect each other's identity and occupation, and the other party will feel your respect and friendliness.

When addressing female college students, we should pay attention to avoid using impolite or discriminatory addresses, such as "little girl" and "little sister", which may arouse others' disgust. If you are not sure about the other person's name or title, you can ask politely. For example, you can say, "What's your name, please? Or "What's your name, please"? This can prevent the other party from feeling embarrassed or uncomfortable.
