Yingxue Reading: Sun Kang had no money to buy lamp oil, so he couldn't read at night and had to go to bed early. He felt it was a pity to let time run away in vain. One night in the middle of the night, he woke up from his sleep. When he turned his head to the window, he found a ray of light coming through the crack of the window. It turns out that it is reflected by the heavy snow, and you can use it to read a book. So he suddenly lost his tiredness, immediately got dressed, took out his books, and went outside. The light of snow reflected on the broad land was much brighter than inside the house. Regardless of the cold, Sun Kang immediately started reading. His hands and feet were frozen, so he got up and ran, rubbing his fingers at the same time. From then on, whenever there was snow at night, he never let go of this good opportunity and studied tirelessly. This spirit of hard study promoted his knowledge to advance by leaps and bounds, and he became a well-educated man.
