Riddle

A peaceful week passed quickly.

Zhang Heng was flipping through a book about photographic composition in the library this afternoon. He then received a call from Shen Xixi.

"Is it convenient to talk now?"

"Wait a minute."

Zhang Heng got up, left the borrowing area, walked into the safe passage, and glanced around. There were only a few freshmen discussing assignments around him, and no one even noticed when he walked past.

Picking up the phone, he asked, "What's the matter?"

"I remember you telling me before that you know how to drive?"

"Yeah."

Zhang Heng knew Shen Xixi wasn't talking about whether he had a driving license, but she spoke of driving skills.

"Can you please help me with something?" Shen Xixi asked, "Heard about the news that was circulating in the forum recently?"

"Sorry, I haven't been on the forum much this week."
