I remember similar scenes during my school years in Korea. By God's grace, I was never hit by my teachers like that. But the teachers used to hit their students like that accusing them of lacking absolute attitude
. They also said that they hit them because they loved
them. The teachers called the stick 'love stick'
that they used to hit the students.
I feel very sorry that such a thing is still happening in Korea. The UBF system of training
is very much similar to Korean education system and its ideals.
