Bernd Wiesberger led by four shots after shooting a 65 in the second round of the Shenzhen International when storms brought a premature end to play for the second day running.
The Austrian had returned to the Genzon Golf Club course on Friday morning to complete his opening round, held over from Thursday after the threat of lightning had led to a suspension which saw several players unable to finish.
After resuming, Wiesberger birdied the 17th en route to carding a 67 that saw him move within one of the lead.
He then picked up seven more shots in the second round to complete the day on 12 under.
