What does 原地踏步 mean in Cantonese?
Actually, 原地踏步 is not a Cantonese phrase, it's just a Chinese phrase. 

The literal meaning is marking time, and it's often used to describe a situation that one doesn't make progress or fall behind.


  班长命令战士们原地踏步.


The squad leader ordered the men to mark time.  


  我要么原地踏步直到获得晋升（这看来得是几年以后的事了），要么改变现在正做的事情。


I could either tread water until I was promoted, which looked to be a few years away, or I could change what I was doing.
