At the end of 1992, Mr. Zhao was hired to work for Verne Q. Powell Flutes, beginning his nearly 25-year flute making career.  During his 13 years at Powell, Mr. Zhao mastered all aspects of flute production, working as a padder, headjoint maker, stringer, and body maker. In 2002, he was promoted to Powell's Vice President of Quality. Since working at Powell, Mr. Zhao has also served as Vice President and General Manager at William S. Haynes Flutes. He has worked as a consultant for many other companies, most notably helping establish the Powell Sonare and Haynes Amadeus factories in China, all the while continuing to produce excellent high-quality flutes. Now Mr. Zhao has started his own flute business, opening his own factory to produce the best quality flutes for the next generation at an affordable price.

Di Zhao's piccolos are all padded with Pisoni pads and are partially shimmed like professional models, and all instruments achieve smooth key action, fast response, and excellent resonance. All headjoints are handcut with undercuts and overcuts, making the sound quality full and easy to play.
