In China, many employees within companies use Chinese instant messaging services to communicate and relay important information to each other. QQ, a computer-based messenger, was the old favorite and can still be seen on many office computers, but newcomer Weixin, which is remarkably similar to WeChat, is becoming increasingly popular. Weixin allows users to record and send voice messages, and for the recipient to play the messages back at their own convenience, making it ideal for business people on the go.
