The frequency of using WeChat has sharply increased from last year and 94% of the users will log in to the app on a daily basis. The vast majority of the WeChat users are Chinese Millennial. Meanwhile, seniors essentially don’t use smartphones. It’s interesting to notice that senior WeChat users prefer to send vocal messages instead of text messages. Probably, it’s because the vast majority of Chinese seniors are likely to be illiterate or they don’t really know how to text using the pinyin system.
