The Life of a J Dog

I was taken in by my father one winter. I thought I would enter a wealthy family. But there is no normal person in this family. They let a dog learn information management, go to sea to do business, and even hunt foreign objects. I can tolerate this. But they actually want me to learn linear equations in two variables! ! !
