"One by one, be careful not to get pinched!" Wang Wenbiao reminded.
Wu Lingyu, imitating Xu Qingfan's movements, placed the sensing plate on the screen. Seemingly worried about getting pinched, she dashed through the door as soon as it opened.
Xu Qingfan noticed that Wu Lingyu kept looking at the ticket booth and asked curiously, "Why do you keep looking over there?"
"I want to see how they buy tickets, so next time I can take the subway with Mom to see Dad!" The little girl said, scratching her head embarrassedly.
Xu Qingfan suddenly recalled the first time he had gone home during the National Day holiday in his freshman year of college, when Xia Xiaoxiao had painstakingly taught him how to take the subway.
"Is there something on my face?" Xia Xiaoxiao, noticing Xu Qingfan staring at her, rubbed her face in confusion.
Xu Qingfan shook his head, "Taking the subway is actually quite simple, you just do this..." he explained patiently to Wu Lingyu.
