The first chapter's first section overused 6 years ago too much that it gave a bad first impression. It seriously looks like word spamming to me. I wish the translator could get rid of couple of unwanted '6 year' repetition. Because to me as a reader the beginning section seriously sucks compared to the quality IET writings. Plain bad quality writing there. But after that it's good. So if u could do something there then it will give a better impression compared to the negative feeling I got.
Thank You
