Yang Shifu, a primary school teacher in Tongboi county of Nanyang city in Henan province, was convicted of sexually assaulting his students between spring 2012 and May 2013.
The teacher was detained by the police after it received tip-offs in the case and investigated the matter, Nanyang City Intermediate People's Court which heard the case said in its judgement, state-run Xinhua reported.
The court, however, postponed the death sentence by two years after which the punishment could be reduced to life imprisonment based on the convict's behaviour during the period.
The case was among a series of sexual assaults reported in primary schools across the country last year, triggering public anger over teachers' misconduct and concerns for the safety of students.
