It is not necessary to include everything in a book. we can have different sectors' history and can be carried out independent research as a specialisation of history. There is nothing wrong if we start history of Dhankuta or Rais or Magars and Gurungs and different languages' history. Here we are emphasising the need of making more people educated about the specific history of different parts through different sources and not only by way of any 50 pages history Book.
