Although it was still the holiday period, once the galley proof of the paper was mailed to Xilin University of Technology, Xu Dajiang arranged an internal review and defense, a defense that took place during the holidays.
Essentially, this could be understood as a mere formality.
Because the project conclusion application had already been submitted earlier with Xu Dajiang's reminder.
This kind of paper, "Mathematics Annual," had already helped the school's professors confirm its quality; the defense was nothing more than a proof that the paper was independently completed by the authors.
Considering that no faculty papers from the Xilin University of Technology School of Mathematics had been published in "Mathematics Annual" before, the professors in charge of the internal project defense were somewhat lacking in confidence.
They prepared a few questions casually, and Qiao Ze, accompanied by Liu Chenfeng, answered them just as casually to complete the process.
