Han shot an 8-under 64 at
Luxehills International Country Club in Chengdu, the capital of Sichuan
province in southwestern China.
One stroke behind were
Northern Ireland's Gareth Maybin, England's James Morrison, Welshman Bradley
Dredge and Denmark's Soren Kjeldsen.
Heavy mist in the morning led
to an hour's delay in play, and 24 players will have to complete the round
early Saturday, including South Africa's Keith Horne at 7 under with four holes
to go.
New Zealand's Steven Alker,
South Korea's Choi Jin-ho and Spain's Sergio Garcia followed with bogey-free
66s.
Also at 6 under were Jeev
Milka Singh of India, Joost Luiten of the Netherlands, Richie Ramsay of
Scotland, Fredrik Andersson Hed of Sweden, Gregory Havret of France, and Danny
Lee of New Zealand.
Three-time major champion
Padraig Harrington opened and closed with birdies but two bogeys left him with
71.
Defending champion Y.E. Yang
had five birdies against one bogey to finish at 68.
China's highest-ranked
golfer, Liang Wenchong, also carded 68 with six birdies and two bogeys.
