Bo was one of a select group of powerful veterans centred on Deng who were informally known as the "Eight Immortals" for their political longevity and for the vast influence they commanded during the 1980s and 1990s. After returning to power Bo supported economic liberalization, but was a moderate conservative politically. He initially supported both Hu Yaobang and the 1989 Tiananmen protesters, but he was eventually persuaded by hardliners to support both Hu's dismissal in 1987 and the use of violence against protesters in 1989.
