WeRun （微信運動） is an app in WeChat.It lets users see their daily step counts.One of its most popular things is a leaderboard （排行榜） among friends that lets users see how their results compared with others.
   As a growing number of people use WeRun，we wondered what we can learn about a person just from knowing their step counts.Here we take a closer look：
   Fewer than 50 steps：Anyone who takes fewer than 50 steps in one day may be ill or sad.Or maybe he or she is just too lazy to get out of the bed!
   50—500 steps：It's easy to have a few hundred steps.Even going shopping on foot will be enough.
   500—8，000 steps：Most students and workers will take between 500 and 8，000 steps a day.These step counts are often in the middle of the leaderboard.But your parents will always give your step counts a thumbs-up （It's their job to care about you!）.
   8，000—30，000 steps：Salespeople and members of film workers are likely to take these many steps a day，as they are always on the move.
   More than 30，000 steps：Mostly，these step counts can be on the top of the leaderboard.They're couriers，porters，cleaners and so on.They're the people who help us live easy and comfortable lives and keep our environment nice and clean.
   To some degree，a person's WeRun data （數(shù)據(jù)） shows his or her character and personal life.But even when actions speak louder than words，we still shouldn't jump to conclusions （結(jié)論）.
