After 1945, Van Mieu - Quoc Tu Giam was the principal worshipping place, so the only activities held at Van Mieu, were offering ceremonies to Confucius and Confucian scholars.  It is noted that President Ho Chi Minh went there to conduct the Autumn offering ceremony on 21^st October 1945 and the Minister of the Interior of the Democratic Republic of Vietnam, Huynh Thuc Khang organized the Autumn offering ceremony on 22^nd September 1946.  These events affirmed the significance of the role and great value of Van Mieu - Quoc Tu Giam for the national culture in a new historical situation.

After September 1946, the organization of offering ceremonies was held according to the national democracy and progressiveness of the government of the Democratic Republic of Vietnam.  An offering ceremony was organized once a year on the date of Confucius’ birth (27 August).  The rules and mode of the conduct of the ceremony were simple.  Instead of lying prostrate, the participants of the ceremony needed to kneel down and they could wear western costumes. The offerings were also simple, practical, mainly flowers and fruit.

During the war of French resistance (1946-1954), Van Mieu - Quoc Tu Giam was almost destroyed.  At the beginning of the national war of colonial resistance (1946-1947), the Khai Thanh Shrine and East and West wings in the Great Sanctuary Section were damaged.

To protect the vestige of Van Mieu - Quoc Tu Giam, some people who had responsibility for the national culture, founded “Van Mieu học Hiệp hội (Van Mieu study Association) with the purpose of the restoration and maintenance of the vestige. “Van Mieu study Association” made a great contribution to the preservation of the vestige until the day of liberation for Hanoi (1954).

In 1954, after taking over the Capital, the Culture branch in Hanoi authorized the restoration of Van Mieu.  The Left and Right wings in Dai Thanh courtyard were then restored.

On April 28, 1962 Van Mieu - Quoc Tu Giam was ranked as a National Historical and Cultural Vestige by the Ministry of Culture of Vietnam.

On April 25, 1988, the Center for Cultural and Scientific Activities Van Mieu - Quoc Tu Giam was founded, its office is located inside the vestige; it assumes the task of preservation, restoration, management and exploitation of the vestige and brings into play the values of Van Mieu - Quoc Tu Giam of building modern Vietnamese culture.
