It had been two days since he donated his manuscripts to Firestone Library.
Lu Zhou contacted a local house cleaning company and cleaned his entire house.
On the third day, he sent an invitation to his Princeton supervisor, friends, and professors to a party in his backyard.
One reason was to say goodbye to Princeton.
The other was to congratulate his students on successfully graduating.
Other than Professor Deligne, Dean Goddard, Fefferman, and Edward Witten, almost half of the Princeton mathematics and physics tenured researchers were all at this party as well.
Because Lu Zhou was pretty sociable, he had a good relationship with most of the people he interacted with.
Because of this, after hearing he was going to leave, a lot of people tried to persuade him to stay.
