    It is believed that social networks allow people to make their online social circle larger. But having 150 friends on WeChat is not the same thing as having 150 friends in real life.

    In last week's Chitchat, we asked our readers how many "friends" did they have in their WeChat account(账户), and how many of them were "actual friends". Here are some of the top comments(评论).

    @left and right

    I have more than 1,000 friends in WeChat. However, the number of "friends" I communicate with daily is less than 50, most of whom are my classmates and families. So many friends are just there and we never speak any word.

    @Kris Wilson Choy

    I have almost 300 friends in my WeChat. However, people who I often send messages to is just 10. Most of these friends are classmates or people who work with me. Except work or studying, we hardly talk with each other during our spare time.

    @Monica

    To be honest, as an English teacher since 1981, I have more than 400 WeChat friends, most of whom are my students, students' parents, and workmates. Although we seldom meet face to face, our ties still remain normal. You see, they often ask me questions online, which I answer happily. Of course, sometimes I feel upset when they ask me to vote (投票) online or give likes. However, I generally do as requested, because it serves to glue our ties.
