The result is based on a report released by Tencent's WeChat, China's most popular messaging app, on its official Weibo account on Wednesday.
For China's post-90s WeChat users, you are likely to get out of bed later in the morning compared with other groups, and the emoji "face with tears of joy" may rule your online social life. Also, your reading materials have shifted from entertainment and gossip three years ago to the current relationship and lifestyle pieces.
And if you were born in the 1980s, your tastes have remained the same, as you are still fond of reading news on national affairs. And "grin" is your emoji of the year.
WeChat users born in the 1970s are called the optimistic group, who like to use the emoji "chuckle" and go through their moments frequently every day. Their bedtime unusually takes place around 11:30 pm.
Users over 55 are the early-bird group with rich entertainment activities in WeChat platforms, such as looking through moments, reading and shopping. They like to cheer up other age groups, so their favourite emoji is "giving a thumbs-up".
The report also indicates that WeChat boasts more than 1.08 billion active users with 45 billion messages being sent and 410 million calls getting through the app each day in 2018.
Also, the app was utilized 1.5 times more over the previous year to pay for meals, with Beijing, Guangzhou and Shenzhen ranked as the top three cities in dining purchases through WeChat.
Since the release of the report, some online users believe that their chat data has been used for big-data analysis, while others are asking where they can attain their own personalized WeChat usage reports.
