Whenever Ms. Zhang receives a series of voice messages on the WeChat messaging app from her mother, the 32-year-old woman looks at them and sighs(叹息). She doesn’t want to listen to them one by one, which can always be over a dozen in all. And she hates having to listen again if she misses something. “I really don't’ want to open them,” she says. ”But what can I do? She’s my mom.”Her mother, however, thinks that texting seems cold, and reading text on a phone screen is difficult for people at her age. So she also uses voice messages when communicating with her old schoolmates.

Now, sending voice messages is seen as a feature for seniors, plus a few groups such as salespeople and drivers. About nine out of 10 Chinese internet users are on WeChat and half of them spend over 90 minutes a day on the app chatting, reading, working and shopping. There is no doubt that WeChat is where China’s national conversation takes place.

WeChat’s 2017 user report shows that while people over 55 made up only 1% of the platform’s(平台) user base, one out of five messages they sent were voice, compared with one in 10 for users under 21.”While users take nine seconds on average to read 100 characters, they need 22 seconds to listen to the same 100 characters,” says Liu Xingliang, head of research at the company Data Center about the China Internet.”Only when you listen to WeChat’ voice messages will you find out how long a minute is,” he says.
