What Happened to the Old Cow in the Courtyard Eating Young Grass?

He Yuzhu looked at the familiar environment with a melancholy look on his face. He didn't look like a fifteen-year-old boy. Like a wise man who has seen through the world. Thinking about his life, it was really miserable. His heartless father, He Daqing, ran away with a widow when he was a teenager. He and his sister were left alone, if he hadn't learned some cooking skills. I'm afraid that the two siblings would have starved to death on the streets. I think he also tried to pass the Fengzeyuan exam, but without exception, how could he pass with his little cooking skills? However, if he were to test again now, he would be 100% confident. Unfortunately, this is a dream after all.
