How to reduce the iPhone system storage?

I used the old iPhone 6 to make a video one day, it says "Not enough storage". When I access iPhone Settings -> General -> iPhone storage, I found my 16 GB phone is showing 11.35GB used by System Storage. It's not normal. How to reduce the iPhone system storage?

Soon I find 70% of system storage space is taken up by "Other" files, it means that iPhone system storage contains the "other" file in iOS 11. If I need to reduce the iPhone system storage, I only need to remove the iPhone Other files.
