Upon hearing Su Bing's question, Gu Zi set aside her work and began to explain. "Let me share a little knowledge with you, my dear. We all grow from children into adults. The period from ten to twenty years old is known as adolescence. During this time, if you notice a significant decline in your vision, accompanied by some signs of puberty such as a deepening voice, noticeable growth in height, and an increased appetite, it's perfectly normal.
"The decline in vision during this period is a normal physiological manifestation of growth. There's no need to be afraid. In time, it will naturally recover. However, from now on, you should remember to sleep early and rise early, reduce your reading and study time. I will also prepare some nourishing food for you. You'll be fine soon."
