Chinese rock and roll's peak popularity was between 1990 and 1993. Many rock bands were established and rock music was performed regularly. Rock and roll was not approved of by the Chinese government because many performers had anti-conformist behaviour. The government made sure that rock and roll was not to be broadcast on CCTV, so the main venues remained to be informal, underground rock parties. Some fans and performers had characteristics such as long hair for males, jeans, silver metal ornaments, black leather coats and hippie-style behaviour.
