Japanese-oriented textbook

Imagine people fake the texts in books
which commonly read by our children............
nanjin mass murder is not an even in which millions of people lost their life!
They just got killed,not died..................
Diaoyu Island is not yet firm on which way,
how could people put them as facts??
History teaches us how to make less mistakes,
we could not just by 'correcting' the 'mistakes' in history to avoid showing mistakes in the past.
Hidden facts are facts,
they will not change in the way they change the texts in the textbooks..
