What surprised Liuliu was that Gong Dafu came to find her as soon as she finished lunch and drank a cup of water, testament to Gong Dafu's brightness and impatience. When Liuliu left, he immediately threw himself into memorising the multiplication table. As a result, in less than half a day, he had learnt it by heart. Liuliu marvelled at the wisdom of the ancients.
Not in a hurry to go home, Liuliu decided to teach Gong Dafu along with his mother. She painstakingly taught him arithmetic, finding herself in an awkward and stressful situation. However, Gong Dafu was extremely excited and enthusiastic. He was amazed by the new ways of calculation that Liuliu taught him. He truly admired Liuliu's intelligence and regretted that her potential was restricted by her gender.
