President Xi Jinping has called on the People's Publishing House to sustain revolutionary legacy and make greater contributions to developing a great socialist culture in China.

Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, made the remarks in a congratulatory letter on the 100th anniversary of the founding of the publishing house.

In his letter, Xi extended sincere greetings to all cadres and staff of the publishing house.

Hailing the publishing house's important contributions over the past 100 years, Xi urged it to keep its emphasis on spreading Marxism and the Party's innovative theories, displaying the progress of the Party and the country, enriching the intellectual and cultural life of the people and deepening reform and innovation.

On Tuesday, a symposium was held in Beijing to mark the 100th anniversary of the founding of the publishing house. Xi's letter was read at the event.

Huang Kunming, a member of the Political Bureau of the CPC Central Committee and head of the Publicity Department of the CPC Central Committee, addressed the symposium.

Huang called for studying and implementing the spirit of Xi's important instructions, and striving to add new luster to the Party's publishing cause.

Founded in September 1921, the People's Publishing House is the first publishing organization founded by the CPC. Its basic task is to publish classic works of Marxism, important documents of the Party and the country, and works of philosophy and social sciences.
