Why did such a zone involve in sadness crime in Japan.
I have said to you so much stress of univesity entrance exam and an bias of university graduation status in top ranking in Japan.
from infant days to 17 years above the enviroment of competition would forse students to blow stolongly with so much stress in terms of mental and phsical.
please imagine such as the screww making prosess.in order to make screw bolts and nuts.after forming the shape of screw.this wiil be put into chamber in heat treatment.at first the screws will be heated in chamber in around 800℃.
what we call this prosess is a temmper prosess . it means purpose of prosess is that screw outside can be harder and stiffness.hoeever inside is frajile and indurable
after that heated the screws will be transfered to the midium range heat chamber 400℃what we call the temper return.this purpose is inside status make more erastic status.from sequence prosessing from 800 to 400 is named harmonized inside quoloty.
I mean by doing so in this prosess inside status of the screw rebirth the stifness and erastisy.more in detai we call the viscoerstic body from above prosess.
to be continued
