Like night and day, past and future, ordinary and extraordinary, calm and turbulent, the world is a process of constant change. In this ever-changing process, people needed to constantly adapt and adjust. Just as we need sunlight to warm the earth during the day and starlight to guide us at night, we also need wisdom and courage to face the changes and challenges of this world. Just like a river, it would become wider, deeper, and stronger with the passage of time. We need to accumulate knowledge, experience, and wisdom like a river in order to find our own way out in the ever-changing world. It was like a flower that had to go through countless trials and tribulations before it bloomed. Only by going through these trials and tribulations could the most beautiful flowers bloom. We need to constantly work hard and struggle in order to bloom our own glory on the road of life. Just like the relationship between wind and rain, the wind brought freedom and freshness, while the rain brought moisture and vitality. We need to interact with each other like the wind and rain to bring about a richer life experience. The world is a constantly changing process. We need to constantly adapt and adjust to find our own position in this ever-changing process and bloom our own brilliance.
