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 bed time 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 favorite emoji is "giving a thumbs-up".
