Musician skill swap

I would like to use my free time to improve my skills and hope someone would like to do it together! We both can learn from each other.

I can offer the below skills:
I am a professional Erhu player ( Erhu is a Chinese instrument, I previously had performance in several famous location).
Mandarin - native level
I live in Golders Green area!
thanks!
