"It's amazing here," Korda said. "It's the Hawaii of China. The course is in great shape."
She made a 65-foot par putt on the par-4 10th.
"Highlight was No. 10," Korda said. "Hit my drive way out right. Didn't hit in the fairway. Then didn't have the right club and the wind took it and I made the putt from across the whole green, from the back of the green to the front of the green."
Michelle Wie and Chinese star Shanshan Feng were a stroke back long with American Brittany Lang, South Africa's Lee-Anne Pace, England's Jodi Ewart-Shadoff and Germany's Caroline Masson.
Wie tied for fifth last week in South Korea in her first start since withdrawing from the Evian Championship in September after reinjuring a stress reaction in her right hand.
"It was fun, because I feel like the ball kind of sits up with this type of grass and I felt like I was hitting flop shots all day," Wie said. "It was kind of fun. I was just blasting them away. Definitely, you have to hit to the right parts."
Wie made an 8-foot birdie putt on the 18th hole that nearly circled the cup before dropping.
"It felt really good. I missed a short one for birdie on 15," Wie said. "Missed a couple of birdie chances coming in. It always feels good when the ball kind of circles the hole 360 and ends up going in. It was a fun round today."
Pace is coming off a playoff victory in the Ladies European Tour's South African Women's Open.
Danielle Kang won a Buick LaCrosse with a hole-in-one on the 155-yard 17th. It was her second ace in competition this season, third overall this year, and seventh in her life. She shot 68.
"I was pretty pumped," Kang said. "My caddie had to tell me to calm down."
Top-ranked Stacy Lewis and No. 2 Inbee Park are skipping the tournament.
Park will take the No. 1 spot from Lewis on Monday. Lewis has held the top position for 21 weeks. She moved to No. 1 on June 2 following her victory in the ShopRite Classic. Before that, Park was No. 1 for 59 weeks.
