Nowadays there is an increasing number of ways of communication which avilialble for people in modern society, like message, telephone and mails. Someone believes that when discussing on upsetting problem, we should use telephone ot voice messages. Someone who opposes it cite that e-mail or text messaging is better, In my view, I prefer the latter one,By talking controversial problems, telephone and vocie messaging can help us express our ideas more clear and easily comprehend by others, Therefore, it can improve our work efficiency. For instance, when I once need to finish a assignmeng on my brand management class,requiring build a vitual brand, our group chooed the voice messaging and telephone to be our ways to communicate. In the process, we had many ideas and many complex problems to talk about,. By using our phones and voice message, we could figure out our brand information and reach aggremernt at a considerably short time. Consequnently, when we finished our assignment fast and high quatity,In addtion, another important advantage of using phones is that , you can let others know yoiur ideas immediately without any delay. One of the best example is the clerks in companies. As we know that, the manager or the CEO always inform their clerks significant information via telephones since it can transmit to the staffs rapidly, and get back inf. On the contrary, if we just send a message or mails, others may not attention it at once. It may have bad influence.
