White-collar workers have fixed working hours, but their contact range is narrow. I suggest that you can mobilize your relatives and friends to pay attention to the object that suits you. Generally, the person introduced by others will definitely ask about each other's personality in many ways. After all, the matchmaker is a small guarantor, and their introduction should be more reliable.

Of course, in order to find like-minded people, it is better to take the initiative to contact yourself. You can get together with friends during the break, or sign up for some young people's activities. Maybe you will meet the right one day, and then you can find out whether the other person's character is reliable.
