Wozniacki, the top-ranked player on the WTA but without a Grand Slam crown, has had a patchy few months, winning a minor pre-US Open title, stalling in the semi-finals of the New York major and then crashing to a second-round loss last week in Tokyo.
Beijing has a special place for the Dane, winner of six titles this season, who first took over the top ranking in the Chinese capital a year ago.
Wary of the first-round upset loss of French Open winner Li Na of China, Wozniacki made sure she came through for victory over her 49th-ranked opponent from the Czech Republic, but not before dropping the first set.
However, the 21-year-old belatedly came good, ignoring nine aces from her opponent, who also sent over seven double-faults. Wozniacki broke six times on her way to victory and a meeting with Australian Jarmila Gajdosova.
In other first-round matches, Zheng Jie earned a welcome home win as she beat Italian Alberta Brianti 4-6, 6-1, 7-5, while Russian Maria Kirilenko, the 2005 winner, beat German Julia Goerges 7-6 (11/9), 6-3.
Virginie Razzano of France reached the second round by beating Argentine Gisela Dulko 6-2, 6-3.
Austrian Tamira Paszek booked the first of the third-round places with her defeat of Czech Petra Cetkovska 1-6, 6-4, 6-2.
Seventh seed and former Roland Garros champion Francesca Schiavone of Italy went out to Slovak Dominika Cibulkova 6-2, 6-2.
