Su Wenwu knew about the South's customs when he first met Ye Feiran. The former knew about the South because he had learned about it from Lan Ruozhu.
Su Wenwu knew he had learned much from Lan Ruozhu. Unfortunately, the latter only stayed at the Su family's house for a while before returning to the deceased royal's mansion.
Lan Ruozhu was thrilled to see Su Wenwu. "You're back! I heard from Binglan that you went to set up your spicy hotpot restaurant."
Su Wenwu said smilingly, "Yes, the mala hotpot Sister made was delicious. It's not as complicated to make, so I planned to open a spicy hotpot restaurant."
Lan Ruozhu nodded and asked, "Is everything ready?"
"Yes, they are. We can open for business tomorrow morning," Su Wenwu added, "Since the Lantern Festival is tomorrow, everyone will go out. I'll take advantage of it to open for business."
