Tangyu shook his head and said, "Grandpa Zhang, it's not as simple as that. If it were that simple, that would be great. Although practice makes perfect, truly remarkable medical skills don't depend on whether you are clever or willing to spend time learning. Real medical prowess depends on talent, and whether you are suited for learning it. If you're not suited, even if you understand the principles, you can't achieve any effectiveness. Just like in martial arts, some can cultivate their skills to perfection, but others will never make it no matter how hard they try. There are many mysteries involved, and I don't know how to explain them to you, Grandpa Zhang."
