To come up with such detailed and clear tables in such a short time is really surprising, and it leads to questions about how she managed to create this table and whether she had guidance from an expert.
Tao Zhijie knew this problem best, as it was he who assigned the task to Xie Wanying, so he explained to everyone, "Teacher Lu only showed her the medical records last night, she had not seen Teacher Zhang's medical records before. I also gave her the task last night. I'm not sure what time she finished writing."
In fact, when she brought her work this morning, he was equally surprised as it seemed she had written too quickly. He had only asked her to write down some suggestions and thoughts, as he didn't quite believe she would be able to figure it out even if he gave her a whole day.
He never expected to open it tonight and see that what she listed were all tables. At that moment, his initial silence and hesitation was due to his inability to understand how she achieved this.
