Having grown tired of her students low grades, the teacher promised to wear the frilly black-and-white outfit if the students scored top marks in their next test, the Daily Mail reported.
And it clearly worked because, true to her word, she arrived in class after the exam in a fancy dress costume complete with a pair of cute cat ears.
According to internet newspaper Rocket News 24, pictures of her apparently taken by one of her pupils appeared online last week.
While critics argued that teachers should not be engaging in such frivolous activities, others praised her for achieving results.
Comments from the Chinese media included “Now that’s a good teacher!” and “The award for 2012 Best Teacher goes to… that girl!”
