Although Hua continued in his leadership role, his power began waning the moment Deng Xiaoping returned to Beijing. The two continued to co-rule for a time, but the latter was rapidly gaining power. With Mao and Zhou Enlai gone, there was no one else in China with his experience and leadership abilities and his ideas seemed fresh and appealing as opposed to Hua's stale promotion of Mao Zedong Thought. Hua was quickly seen as being nothing more than a vacuous party hack with no ideas of his own. This was reflected in the 1978 constitution, which still contained references to proletarian internationalism and continuous revolution. As Vice-Premier in charge of Technology and Education, Deng restored the University Entrance Examinations in 1977, opening the doors of post-secondary education to nearly a generation of youth who lacked this opportunity because of the Cultural Revolution. He elevated the social status of intellectuals from the lows of the Cultural Revolution to becoming an "integral part of socialist construction."
