With so many graduates in a class, it's impossible for all graduates to go up on stage to receive their diplomas from the school leaders personally, or else it would take until the sun sets in the west. Therefore, only a predetermined set of dozens of students were arranged to come up to the stage in sequence.
The school leaders awarded the diplomas to the graduates and then flipped the tassel on their mortarboards, signifying that they had graduated! The school leader doing this for Mu Xiangwan happened to be the nearly seventy-year-old principal. Knowing Mu Xiangwan's identity, after flipping the tassel, they shook hands. Mu Xiangwan bowed respectfully to express her gratitude, and the principal said something profound: "Mu Xiangwan, congratulations on your double happiness!"
