It appears more than the Hallyu phenomenon is being culturally exchanged between China and Korea. Rampant cheating in Chinese classrooms has caused the government to implement harsh measures to crack down on this behavior:

Punishments will depend on the "impact on society" of individual infractions, Xinhua said, citing a draft of the law now before the Law and Politics Committee of the State Council, China’s cabinet. Relatively minor violations could result in a fine, while large-scale organized cheating could result in the maximum sentence along with additional punishments that weren’t described.

Last year’s cheating incidents in Henan used cell phones messages to send answers to students taking the three-day national university entrance exam. Students and teachers used text messages and digital cameras to pass questions to other teachers outside the exam hall who looked up the answers and messaged them to students who paid for them.

At least seven teachers and five students were arrested, though details of the charges or punishments they face were not disclosed. Other scams have involved switching exam papers and the use of "hired guns" — brainy students paid to take exams for others.

From the Horse’s Mouth it seems Chinese teachers approach their jobs just like Korean teachers do:

Now that’s what I’m talking about. You’ve got to admit, whenever the government decides to lay down the law - they go all the way! Unfortunately, the students aren’t going to know what hit them if they are caught cheating because it is completely tolerate and even encouraged in the lower levels of education from elementary to high school. High scores make the teachers look good and it makes the school look good.

Cheating in Korean classrooms is a continuing problem that shows little signs of improvement no matter how many proclamations the government makes against it.  Every year during the National Exam time frame the newspapers are filled with stories of the latest exam cheating scams.  The papers are also equally filled of stories of students who probably didn’t cheat and failed the test so they decided to commit suicide by jumping off the top of an apartment building. 

As long as a student’s future college and career ambitions are subject to the results of one test, students will continue to find ways to cheat on these tests.  Also keep in mind it isn’t just the students impacted by the results of the tests.  Teachers are judged by how well their students score on the test and parents, particularly mothers in Korea, are judged by family and peers on how well their children perform in school.  As long as the two parts of society that should be condemning cheating have so much riding on how well their children perform on these exams, they have little interest in cracking down on cheaters.  Is the western style education system better than the Asian system of National Exams?  That I don’t know, but what I do know is that children in western schools are not throwing themselves out of apartment buildings.
