In 1978 Fang was assigned to host Ruffini, a guest of the Chinese Academy of Sciences. They gave joint university lectures and developed a profound friendship. In 1981 in China they published a small book introducing relativistic astrophysics that became revered among astrophysics students. In 1982 Fang and Ruffini organized the first international conference on astrophysics in China—the third Marcel Grossmann Meeting—and thereafter remained organizers of the Grossmann meetings. Together with Abdus Salam, Riccardo Giacconi, George Coyne, and Francis Everitt, they founded the International Center for Relativistic Astrophysics (ICRA) in 1985. Physics Today
