By introducing ourselves, we have actually got to know each other. At this time, please remember, and call each other's names at the right time, preferably intimate names, such as Xiaozhen and Yongbo, to make each other feel familiar and intimate, which will help to warm up their feelings. In communication, information exchange should be two-way. Therefore, when someone tells you a news or story, it's best to tell them something new that you know, and "reciprocate" to find a topic and exchange information.
