(Beijing, November 19) Chinese boxer Zhang Zhilei, in his +91kg quarterfinal of the "Good Luck Beijing" 2007 International Boxing Tournament this evening at the Beijing Workers' Indoor Arena, won a four round unanimous victory over Anders Ruiz of Mexico 28-9.

Zhang Zhilei, dubbed as "iron fist prince" in local media, took control early in the bout, landing powerful shots to secure the win. The scores were 8-3, 7-3, 4-2 and 9-1.

However, Zhang said he wasn't satisfied with his performance.

"I just finished the Chicago World Championships and had some problems in physical strength. I was tired today and didn't do well." Zhang noted, rubbing sweat off his face.

Zhang Zhilei took a bronze medal in the +91kg category of the 2007 Boxing World Championships which concluded early this month and secured a berth for host China in the boxing competition of the 2008 Beijing Olympic Games.
