"Doctor Yu, do you have time?" Zuo Cidian knocked and opened the door. Then he greeted Yu Yuan in a familiar manner. 

Yu Yuan stood in front of a light box to read scans. She was surprised and turned around to look at Zuo Cidian.

Both of them stared into each other's eyes for ten seconds before they burst into laughter.

"Old Zuo, your brain isn't really there today, right? You're asking me whether we have time?" Yu Yuan laughed like she was a pair of torn rubber gloves.

Zuo Cidian could not help but laugh, and he laughed like he was a used piece of gauze. "I asked on behalf of Doctor Ling."

"You should have said that earlier." Yu Yuan stopped laughing immediately. She looked behind Zuo Cidian. Then, she sighed in relief when she did not see Ling Ran. "Next time, you should tell what you want to say directly. Don't ask if I am free."

"I know. This is my bad habit." Zuo Cidian waved his hands. "I'll send you a photo."
