"Dongyu, you have come here!" The teaching assistant chased after her, flustered and exasperated: "You have the professor worried!"
"I'm sorry..." Dayu made a silly face, "I was chasing a frog and ended up at Grandma's house..."
By now, the professor had also arrived. He was wearing reading glasses, and his hair and beard were snowy white, making him look as affectionate and adorable as Santa Claus.
Dayu ran up to the professor: "Professor Zhong, I'm sorry to have made you worry. I was chasing a frog and just ran over here..."
Song Xiaoyin was utterly astonished as she gazed at the elderly man with hair and beard as white as snow. She stepped forward, excitedly exclaiming, "You... Are you the college professor Zhong who once taught at A University?"
"Yes, I am Zhong Hanbang!" the professor said.
