What I use the most often now is WeChat. It is a mobile text and voice messaging communication service developed by Tencent in China, first released in January 2011. It is the largest standalone messaging app by monthly active users. It is the newest app among the three, but probably has the most users now. WeChat provides text messaging, hold-to-talk voice messaging, broadcast (one-tomany) messaging, sharing of photographs and videos, and location sharing. Photographs may also be embellished with filters and captions, and a machine translation service is available. So I use it to send text messages, voices, photos both for fun and for work.

Besides the above-mentioned communications channels, we have QQ, Microblog, WeChat, etc. The first one I used is QQ, because it first came into existence. The biggest advantage of it is that it enables me to send large attachments. I still use it now when I am in front of the computer. I also use Microblog, but I use it less often now, because not many people use it now. This implies one’s choice of communications channels is affected by others. Its main function, I think, is like a diary, which is a record of what I do, and what I think. It is also focused on current social events.
