Chatting up is a common social way on campus, but please note that it is very important to respect each other and treat each other honestly. Here are some suggestions to help you strike up a conversation on campus:

1. Self-confidence: Make sure you are confident before chatting up. A confident attitude will make you more attractive.

2. Start naturally: find a suitable topic, such as asking if the other person has joined a club or is taking a course.

3. Be friendly: Be friendly and enthusiastic when chatting up people to make them feel comfortable.

4. Listen: During the dialogue, pay full attention to each other, listen to their views and interests, and show your respect.

5. Keep it easy: Don't be too nervous and try to let the conversation go naturally.

6. Say goodbye at the right time: If the other party shows signs of disinterest or discomfort, end the conversation at the right time to avoid putting pressure on the other party.

7. Respect each other: Don't force each other to do things they don't want to do, and respect each other's choices.

8. Be polite: Regardless of the outcome, be polite and respect each other's feelings.

Finally, please remember that chatting up is just a social way, and don't regard it as the only way to pursue each other. There are many other ways to meet new friends on campus, such as participating in club activities and taking classes.
