Authorities shot dead one of the suspects and caught the other one, who was wounded.

Chen Huichao, a police officer, said that he had to fire his gun three times, while another officer fired five shots at the suspects.

Chen, whose left thumb was injured in the incident, admits firing at the suspects, who were dangerous because of the risk of hurting the fleeing woman and child.

The police said the woman and child even fell to the ground during the chase.

The woman and the child were not hurt but the injured attacker and others injured are now confined at the General Hospital of Guangzhou Military Area Command of the People's Liberation Army, reports China.org.

Four of the nine injured victims were still in the emergency room as of 11:30 am. Six others, including the suspect, were declared in stable condition.

The station, which also had a similar knife attack on May 6, 2014, is back to normal operations.

The police are investigating the case and were bent on establishing the identity of the suspects.

Outside Guangzhou, a mass stabbing occurred at the train station in Kunming City in March 2014, killing 26 people and wounding 140 people.

These knife attacks, often on school children, have shocked China since violent crimes are relatively rare in China compared to other countries, reports Reuters.
