Remember the Old Era
New Era exists due to Old Era
Old Era is platform of Old Tradition ,Culture and Human Values
New Things is built to renovate the Old Things
But function of Old Things does not destroy's
Even though it becomes New Things
New Things gives new feature to Old One.
Similarly Old Era prefer it own values and rules ,it does not destroy it function.
New Era gives new edition and new values to human kinds
But it does not affects the Old Era
We should remember the both Era
The Old One & The New One
World depends and leaves  with both the Era
