Feng's dramatic 72nd-hole eagle Sunday gave her a one-stroke win over Stacy Lewis in Beijing while Inbee Park was third but five strokes behind Feng.
Feng moves up from ninth to eighth in the rankings because of the win, her first since last December when she was first at the Omega Dubai Ladies Masters on the Ladies European Tour.
Her improvement of one spot in the rankings pulls her close to No. 7 Karrie Webb in the rankings.
Catriona Matthew's move from 10th to ninth was reflected in the drop of I.K. Kim two places to 10th due to a revaluation of points from previous tournaments. They are just 0.03 points apart in ranking points average.
Ryu So-yeon tied for 10th in Beijing and edges past Lydia Ko for the No. 4 spot. Ko is fifth but there is only 0.02 points difference in their averages.
Park remains atop the rankings with Suzann Pettersen in second and Lewis moving closer after her strong finish in Beijing.
The LPGA continues its Asian swing this week with the Sime Darby LPGA Malaysia tournament. Park won the event last year.
