Dear @mahadisalim,,

Books always inform us about new and unknown things. Which is very important for all of us. Because we all need a lot of interest and need to learn new things. Like you didn't know anything about electricity at the beginning of learning about electrical. But AK Theraj and B. After reading L Theraj's book you have got a good idea about electricity.

We really need a book to give employment opportunities to the unemployed people in Bangladesh at this time. I hope we will get a good book on unemployment relief from you.
