1. Reading (读书): Gaining knowledge and learning from the experiences of others throughout history.
2. **Traveling (行路):** Experiencing different cultures, places, and ways of life firsthand. 3. **Meeting People (阅人):** Interacting with diverse individuals to understand different perspectives. * **Comparison to Western Concepts:** The Western concept of being "worldly" or "open-minded" is similar, but **眼界 (yǎnjiè)** is more profound and internally focused. Being "worldly" can sometimes imply a certain sophistication or status from having traveled. In contrast, `yǎnjiè` is about the fundamental //change in mindset// that results from new experiences. A humble scholar who has read thousands of books but never left his village can be said to have a vast `yǎnjiè`. It's less about the "what you did" and more about "how it expanded your capacity to think." A person with a wide `yǎnjiè` is not just knowledgeable; they are less likely to be tripped up by minor setbacks because they can see a much larger context.
