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 favorite 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.

In addition to covering users' socializing, WeChat has gradually penetrated into our daily lives. Compared to the year before, people used WeChat 4.7 times more to purchase public transport tickets, and 2.9 times more to pay for medical expenses.

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.
