2. Source: Ming Dynasty's anonymous "Zengguang Xianwen": "Reading must be intentional. In a word, it is worth thousands of dollars. Say something to everyone, but you can't throw away all my heart. Plant flowers intentionally, but not unintentionally. It is difficult to draw a tiger's skin but a bone, and people know its face but not its heart. "
3. Translation: If you want to be outstanding in literary talent, you have to work hard at school. Leave room when talking to others, and don't say everything you want to say. Flowers planted with heart often don't bloom, and willows planted unintentionally often grow into shadows. It is easy to draw the shape of a tiger, but difficult to draw the skeleton. It is easy to be familiar with a person's appearance, but it is difficult to know a person's heart.
