Goals from Shu Chang and Han Peng helped the home Shandong side get an upper hand early in the game, while playmaker Du Zhenyu's absence made the just-promoted Changchun team hardly pose a threat.

The loss also enlarged the gap to six points between the tally leader Shandong and the second-placed Changchun, which had only seven against-goals before the duel.
