Finding a Xiao teacher

[workev]

Hi, I got a xiao for Christmas, does anyone know of a teacher in the UK. I’m getting music out of it, even on the second octave, but sounds a bit windy, so I would like some help putting this right before I get into too many bad habits. My fingers cover the holes no problems, so I know it’s my mouth or lip positions that are at fault. 

Any advice would be gratefully welcomed
