Sun Liyong (ri9ght) and Sun Yi pose for a photo in their home in the Sydney suburb of Campsie, Australia. Sun Yi's father was a Tiananmen-era dissident who was imprisoned for openly criticizing the crackdown. She admires her father, but wonders if his sacrifices, a broken marriage and seven years in jail, were worth it. AP Photo/Rick Rycroft
