Hong Kong's Taichi Kho on Friday took the outright lead midway through his first professional golf tournament on home soil.
The Asian tour rookie fired in six birdies for a second round of 64 at the World City Championship.
That left him at 12-under par – two shots clear of the Philippines' Miguell Tabuena heading into the weekend.
Michael Hendry of New Zealand was alone in third at 8-under par.
