Once, there was a wealthy man who had a son more interested in playing than studying. The father forced him to stay in the “study room” to read books, and then he secretly listened in.
After a while, the son exclaimed:
– This is amazing! I understand now.
The father was very pleased and entered to ask:
– Which part of the book did you find so interesting? Show me.
The young master replied:
– Father, I believe that reading books is truly beneficial; it expands the mind greatly. For a long time, I thought books were just written words, but now that I look closely, they are indeed printed letters.
