Feng has not won since her breakthrough triumph, but she changed her clubs last week to those of Japanese manufacturer Honma and finished second at the ShopRite LPGA Classic.
"I'm really excited about this week because last week I had a good finish, and I think I'm ready for this week," Feng said.
The course, she said, looks ready to challenge the LPGA's top players.
"Scores won't be too low, I don't think," Feng said. "The fairways are just as narrow. The greens are actually maybe a little faster and the rough is really, really thick.
"Last year the reason I won was the final day I hit 17 fairways, and the only one that I missed the fairway, I made a birdie. So the longer the better."
Feng's goal is to claim the world No 1 ranking now held by South Korean Park In-Bee, who won this year's first major title at the Kraft Nabisco Championship.
"I still can't believe I'm No 1," Park said. "It's tough to believe that I am the top player of this great tour. This is a world tour with so many different players representing so many different countries.
"It's still a big fight for the number one player every week and it could change every week. We are really good for each other, we inspire each other and that's very good for the tour."
World No 3 Choi Na-Yeon, the US Women's Open champion, is also in the title hunt.
"I like to play these difficult courses," she said. "It's just different mind-set. I have to be really patient until the last hole. I need to accept every situation."
