The next morning, Ming learns that the hammer that his sister accidentally dropped is actually the one that was given to her by the Shaoguan family at the exhibition of the new alloy. Ming and his father discuss the significance of giving the hammer to his sister, and Ming reveals that his father's motives for making the call are to confirm Ming's feelings for his sister. Ming also reveals that he received a message from his brother the previous night, saying that he had found the sample of the alloy under the tree, and wanted to lend it to Ming. Ming explains that his brother is a "research lunatic" who does not know anything about romance. Ming says that the elders of both families are desperate to make the two of them an item, but Ming will not allow his father to "mes around" with his sister
