Others could address her as junior because of their magnanimity, which naturally also stemmed from Old Madam Yu's words.
But it certainly wouldn't be appropriate for her to address others as senior.
Professor Chen seemed to notice her hesitation and smiled.
"It's fine, junior can call me Senior Chen, I'm the head of the Chinese department at Medical University, and we'll be seeing each other often. By the way, you're a student at Medical University, right?"
"Senior Chen, I am indeed a student here."
Tang Shu obediently accepted this form of address.
She knew that if she were to call him Director Chen again, it might create a distance between them.
Having been a disciple for so long, this was the first time she had met any of Teacher Yu's other students, which felt quite novel.
