Oh, dude, you're talking about Karachi! Yeah, it's got those 21 dots on its flag that apparently represent the 21 administrative units of the city. So, if you ever see a flag with 21 dots and wonder where it's from, it's Karachi, my friend. Like, who knew dots could be so symbolic, right?

Which city of sindh has 21 dots？-Oh boy, that's a tricky one! Sindh is a province in Pakistan and I'm not sure which city specifically is associated with having 21 dots. Maybe you could give me a little more context or clarify what you mean by \21 dots\ I really want to help you out but I just don't have that specific information right off the top of my head. It could be a very unique or local reference that I'm not familiar with.
