"Uncle." Zhang Shuping called out to Zhang Huayao and felt it was inappropriate, so he corrected himself, "Doctor Zhang, Dr. Xie has arrived. Also, Teacher Fang has come to visit grandma and would like to meet you."
"Hello, Doctor Zhang." Fang Xueqing extended her hand to Zhang Huayao to shake hands as she entered.
"Hello, hello, Teacher Fang." Zhang Huayao did not shake her hand but politely asked someone to move a chair for her, "Please, have a seat."
