Finally Sir was back from his journey 🙂 and he did asked everyone
about what was going on. He discussed with me too.

I was working on the printing of the book. I told Sir about the
problems, that how the copy-pasted content was all distorted and I had
manually set the things. Sir told let the LaTeX for you as there is no
need to do the things manually. He also that we people don’t know how
to use the things.

And now proceeding according to the Sir’s intructions.
