Jacquelin had five birdies and two bogeys on his round at the Shanghai Silport Golf Club while Huang bounced back after bogeys on his first three holes. They are one stroke ahead of Gary Rusnak. A group of 11 golfers finished the first round at one-under 70.
"I said to my caddie as we set out, anything under par will be good so just try and par every hole," said Jacquelin in reference to the course conditions. "Par would have been a good score and three-under is even better. It is going to be tough to score under par so you just have to try and save pars on every hole."
Huang, three over after three holes, birdied four consecutive holes midway through his round and grabbed the lead with a birdie on No. 18.
Jacquelin was as low as four-under on the day but bogeys on 14 and 17 dropped him back. He also birdied 18 to share the lead.
