In the bathroom, there was a long silence.

Ma Li said faintly, "To put it simply, isn't it just watching someone pee?"

"It's too vulgar. Science, we have to use scientific terms." Ma Li's sister wiped her saliva and stood up, expressionless. "When a guest comes to our house, we have the obligation to pay attention to the guest's health."

Ma Li: "Does it also include urinary health?"

"That's right." Ma Li's sister nodded seriously, and then reached out her hand to Chen Yu, pretending that nothing had happened. "Hello, we meet again. Let me introduce myself. My name is Ma Yan."

Chen Yu: "..."

"Don't be nervous." Ma Yan waved the camera in her hand. "If you don't like it, then we won't be at ease."

"You... Hello..." Chen Yu reached out to shake the other party's hand and immediately pulled it back. "Don't be uneasy. My mother told me not to let the good water flow to others' fields. If there's pee, I'll hold it back and go home."
