Chinese boxer Zou Shiming made the best of his US debut on Saturday night at Madison Square Garden.

Zou, 35, the World Boxing Organization international flyweight champion, scored a 10-round unanimous decision over 19-year-old Jozsef Ajtai of Hungary.

Zou, a two-time Olympic gold medalist for China, seemed frustrated at times during the fight, stalking the energetic Ajtai through most of it. Zou's best round was probably the eighth, when he landed two left uppercuts and a right cross. Zou also scored well in the third round.

Still, the younger fighter never seemed hurt in the fight, but didn't pursue Zou with any menace. Zou also closed off the ring well.

The crowd booed some of the action, as Ajtai frequently held Zou. Some of the Chinese fans were chanting "Zouuuu", offsetting some of the boos.

Jiang Sicheng, a staff member at New York University, was holding a Chinese flag. Jiang said he has followed Zou for several years and bought his tickets early.

"I hope he can spread his reputation in the US, so it will be great for him to go international," Jiang said.

"I learned about this match from Chinese news about two days before, then I ordered two tickets immediately for me and my dad to support Zou,” said Li Zhi, a post-doctoral researcher at NYU. "My dad came to visit me from China; he is a fan of boxing."

"The vibe here is really good, which is kind of different from China’s," Li's father said.

The Chinese fans got a taste of boxing New York-style, as two of the bouts before the raucous crowd paired fighters from Puerto Rico and Mexico.
