Pen Zen is a 22-years-old diabolist from Taiwan who started diabolo at the age of 7. He trained at the National Taiwan college of performing arts. He is part of the MHD crew and has been performing both in groups and as a solo artist. He is arguably the most technical diabolist in the world, notably for being the first person to self-start and control 5 diabolo low in 2016. 

He achieved several world records over the years. In recent time, he performed at the 42nd Cirque de Demain Festival in Paris. Pen demonstrated a perfectly timed, dropless and possibly the most technical diabolo act ever performed. He performed in the Flic Flac circus in Germany and is now part of the new ECHO show by Cirque du Soleil.
