Police shot one of the attackers at the train station in the southern metropolis of Guangzhou, the city's public security bureau said in a statement on its microblog, adding all six injured had been hospitalised.
Four attackers were involved, the People's Daily newspaper reported on its verified microblog, adding they were wearing white caps and police opened fire on them after they ignored warnings.
One of the men died, one was arrested, and two escaped, said the newspaper, the official mouthpiece of the Communist Party.
It also follows a March attack at a railway station in the southwestern city of Kunming, in which machete-wielding attackers killed 29 people and wounded 143 in what many in China have dubbed the country's "9/11".
