Why didn't Lu Yu invite Lang Xianping to the appointment?

Professor Lang Xianping mentioned Lu Yu in his program, which shows that he still likes Lu Yu's appointment program and Lu Yu himself. I think it's not that Lu Yu didn't invite him, but that he didn't want to talk about his personal life (which was mentioned in the last question session of Tsinghua's speech), so he didn't attend Lu Yu's appointment, but I believe many people would like to see Professor Lang on Lu Yu's program, and I hope to see him in the future!
