TIPS: Wherever you see those small shimmering and glittering lights, it can give you an opportunity for a wonderful bokeh.
- Just point the camera towards those lights
- Have the smallest possible aperture setting (could be f32)
- Have the shutter speed very fast (ideally 1/4000)
- Don't even worry about focusing, put your camera in manual focus mode
- Compose the frame
- Twist the ring of focusing till you get the desired size of the bokeh
