The first leaders of the People's Republic of China were born into the traditional imperial order but were influenced by the May Fourth Movement and reformist ideals. They sought to change some traditional aspects of Chinese culture, such as rural land tenure, sexism, and the Confucian system of education, while preserving others, such as the family structure and culture of obedience to the state. Some observers see the period following the establishment of the PRC in 1949 as a continuation of traditional Chinese dynastic history, while others claim that the Communist Party's rule has damaged the foundations of Chinese culture, especially through political movements such as the Cultural Revolution of the 1960s, where many aspects of traditional culture were destroyed, having been denounced as "regressive and harmful" or "vestiges of feudalism". Many important aspects of traditional Chinese morals and culture, such as Confucianism, art, literature, and performing arts like Peking opera, were altered to conform to government policies and propaganda at the time. Access to foreign media remains heavily restricted.
