A soft ruler is an elastic object. Just like a stick can lift a piece of wood. The resilience is amazing. The first fight is the first contact. The force is relative and will rebound after being stressed. In addition, the flexible ruler also has some toughness. There will be a speed when it bounces off, because it needs a quick reply. It is conceivable that speed plus strength, this is how much strength.

The exposer is a student once taught by Ding Moumou, the class teacher involved. It is necessary to mention that the students' attitude towards this teacher can only be described in one word: fear is more appropriate than fear.

The reason why this happens is related to Mr. Ding's educational methods. The exposed graduates said that Mr. Ding would hit students' hands and faces with a soft ruler, and it is common to hit children's faces with a soft ruler. In addition, the number of times you hit your child in the face with a soft ruler is not less. The reason why the soft ruler is used is because it hurts people more and leaves no trace.

According to the graduate, I learned that Mr. Ding not only used soft rulers to educate students, but also bought many soft rulers for substitute teachers in various subjects. Everyone knows what these soft rulers are for, and they are definitely not used as normal rulers, but students have never seen other teachers use them.
