It was Cheng Jinyan. Jiang Yao was a little surprised. She thought he might have called because of her pregnancy, so she hesitated to answer it.
Cheng Jinyan represented the Cheng family. She did not know whether he made the call himself or on behalf of someone else.
"Director Jiang, the phone has been ringing for so long. Why aren't you picking it up?" Xiao An asked in confusion. "It's ringing again. They've called twice. Something must be wrong."
Jiang Yao pressed the answer button and said in a slightly muffled voice, "Hello?"
"Did you bring people to the Medical Research Conference?" Cheng Jinyan sounded a little flustered.
"Yes."
Jiang Yao knew that he already knew her answer, but she did not expose him since he did not ask about her baby. However, when he asked about the medical research conference in a strange tone, Jiang Yao felt that it was a little odd.
