Like Luo Wenxuan said, this was an invitation letter.
Technically, this invitation letter was not sent to Lu Zhou personally. It was sent to the ILHCRC under the name of CERN.
Inside the invitation letter, CERN proposed to launch a world physicists summit named the "Century of Physics". They hoped that the ILHCRC could act as the main organizer of the conference and cooperate with other major particle physics institutes as well as top scholars around the world to discuss the future of physics.
After listening to Luo Wenxuan's explanation, Lu Zhou was very surprised.
Cooperating with major particle physics institutes around the world to discuss the future of physics for the next century was such an important event. He did not expect that CERN would give the opportunity to the ILHCRC to host it.
But after thinking about it carefully, it made sense.
