Hua's reliance on Maoist orthodoxy led him to continue a cult of personality surrounding his own image alongside Mao's, equating his presence to that of Mao, but pinpointing the focus at a nominally separate era. To provide for distinct identity, Hua attempted his own change of the Chinese written language by further simplifying characters. A small number of these Hua-era simplifications continue to be in use informally, as there was no formal sanction of their legitimacy after Hua left office. In early 1977, the National Anthem was changed to reflect pure communist ideology rather than revolutionary drive, inserting lyrics exclusively dealing with Mao Zedong Thought and building an ideal socialist nation, as opposed to the wartime patriotism reflected by the original lyrics.
