Mrs. Bear's answer is intended to

You don't get a scholar until you are seventy. It seems that there is no future with you in the future, and I can only rely on you to grow old.

Jokes have allusions. Once upon a time, there was a scholar who was almost seventy years old when his wife suddenly gave birth to a son. The son was born because he was too old, so he was named "Age". Soon, another son was born. Like a good scholar, he was named "Xue". In the second year, another son was born. The scholar smiled awkwardly and said, "It's a joke to have a child at such a big age!" So he named it "Joke". When the three sons grew up with nothing to do, the scholar let them all go into the mountains to get firewood. After they came back, the scholar asked his wife, "Three sons, who played more firewood?" The wife replied, "I am old and have no knowledge at all, but I have the burden of jokes."
