A national flag is a symbol of an independent country. We have a national flag of our own. It symbolizes our integrity, solidarity and sovereignty. We got our national flag at the cost of a bloody war in 1971. Its shape is rectangular. The length and breadth of it is 10 : 6. It is made of cotton, linen or silk. The major part of it is deep green and there is a red circle in the middle of it. The deep green is the symbol of everlasting youth, freshness and vigour of our nation. The red circle symbolizes the rising sun of independence. It is hoisted everyday on our government offices and educational institutions. It is kept half-mast on our national mourning days. We should uphold its honour by doing our work honestly and sincerely.
