Regarding Shi Touyu's confusion, Yu Liumei explained it this way.
"I've said it before, the way one treats those sitting at the same table while eating says a lot about a person's character. Why did I notice her? When I went to the bathroom halfway through the meal, I heard her on the phone, telling a girl that looking thin is good-looking. When I came out of the bathroom, I saw this scheming woman piling pig intestines on the girl next to her! She says being thin looks good but gives fattening food to others. Clearly a calculating girl. Also, as I walked past their table, I noticed there were only three large shrimps left. I saw her pretend to be enthusiastic in giving away the smaller ones, while acting generous, and eating the largest one herself in the end! That's why she's the worst!"
Through a foodie's eyes, these events that happened within seconds are enough to judge one's character.
Shi Touyu was amazed by Meizi's magical theory, while Xiao Qian was amused.
"You win."
