I have read your full post. By reading your post, I came to know that the Bangladesh got independence on 16 December 1971. The flag was designed by Shivanarayan Das. And you are right their are alot of emotions attached to the flag of our country. Green color represents the greenery and landscapes of Bangladesh and red circle represents the blood of soldiers who didn't care for their lives and fought for their country. Bangladesh flag represents their country in different ways like mostly in cricket because it's a famous game there. I also love to watch their matches.
