China's top boxing prospect Zou Shiming started his Olympic campaign with a comfortable win over Venezuela's Eduard Bermudez Salas to deafening roars from a partisan crowd on Wednesday.

Some 8,000 fans at the Workers' Gymnasium went wild when the scoreboard showed 11-2 for the local light-flyweight after a one-sided bout.

The 27-year-old Zou stepped up a gear after a cautious first round and firmly took control from the second, during which Bermudez Salas received a standing count.
