Although Qin Zhi'ai's mother had invited Gu Yusheng and Xiaowang to have dinner at her home, she did not have much in the way of ingredients.
When they arrived at her apartment, she warmly welcomed Gu Yusheng and Xiaowang into the living room, invited them to sit on the sofa, and poured some tea for them. She then asked Qin Zhi'ai to accompany her to the community supermarket for groceries.
On the way to Qin Zhi'ai's house, Gu Yusheng had seen a large shopping mall not far away. After Qin Zhi'ai and her mother left, he told Qin Jiayan, "I need to step out and make a call." He then signaled to Xiaowang to follow him, and they left the apartment together.
Because the mall was not too far, and Gu Yusheng was afraid Qin Zhi'ai and her mother would notice his car was gone if they returned before him, he decided to walk to the shopping mall with Xiaowang.
