Chan says he has always wanted to be a role model to children, and has remained popular with them due to his good-natured acting style. He has generally refused to play villains and has been very restrained in using swear words in his films – he persuaded the director of "Rush Hour" to take "fuck" out of the script. Chan's greatest regret in life is not having received a proper education, inspiring him to fund educational institutions around the world. He funded the construction of the Jackie Chan Science Centre at the Australian National University and the establishment of schools in poor regions of China.
