May I ask the origin of Lao Wang next door?

From a joke, a couple gave birth to a child named Xiao Bai. . . Xiaobai grew up and began to learn to speak. In order to make the old man at home happy, teach him to call him "grandpa" first. . . Xiaobai called "Grandpa Grandpa". Two days later, Grandpa passed away. .

This family taught Xiao Bai to call "grandma", and Xiao Bai quickly learned to call "grandma". As a result, two days later, grandma passed away. . .

Next, it's the turn to learn to shout "Dad". Xiaobai's father is very nervous. . He immediately learned to shout "Dad". For the next two days, Dad stayed up all night and couldn't sleep well. . . As a result, two days later, Lao Wang next door died. . .

There is also a saying that in big-headed sons and small-headed fathers,

In one episode, their family invited uncle Wang next door to dinner. As a result, uncle Wang came and found that he looked exactly like his big head son, hahahaha.
