Don't make a hasty decision. If the first impression is not so bad, there is still the feeling of sitting down and talking. Then continue to chat, or leave a phone number and get to know each other when you come back. Don't rush to decide whether to do it or not, and don't leave yourself with a regretful decision.
3. Pay attention to details. Make a good impression on each other. Details are important. For example, if the other person has been looking at the mobile phone, then don't talk, because you are not important in the other person's heart. In other words, when you are talking, the other person is absent-minded, so don't talk. In addition, in dress, don't be unconventional, don't be too avant-garde, and be clean and tidy.
