The Mafia King is efficient in diaper change

Wei was returning back to his office after attending a meeting from someplace else. He was checking his phone to search for more toys for his twins and buy them today. He saw a life size fluffy panda bear on one shop's website, and his gaze sparkled thinking how the twins would definitely love cuddling it.

He said to the driver, "Drive to this shop's location."

"Yes, Boss."

At a traffic signal as his car stopped, he noticed a crowd around a certain restaurant and the people passing by whispering and talking among themselves as if something serious had happened.

At first, Wei didn't pay much attention but when he recognized the minions from the underworld gangs rushing inside the restaurant carrying huge bags in both of their hands, he wondered what the minions gang was doing here? They were supposed to be at the base with Lihua. He also caught the word 'diaper' on one of the packet's labeling and tilted his head.

Why would they bring diapers?
