Abstract: President Ho Chi Minh practiced the complete transition of Vietnamese patriotism from tradition to modernity - patriotism based on the viewpoint of the working class - patriotism connected with socialism.

Among these contents, developing the spirit of national solidarity in national construction and defense was always his top priority. Great national unity is a revolutionary approach.
