After a while, Liu Qian finally stopped crying.
She pointed to the stream and said to Zhang Xiaohua: "Xiaohua, look at this river. It starts from its source as just a small trickle of water, flowing along the riverbed, gathering more streams along the way, it grows longer and larger. Gradually, it will become a big river, a great river, and finally flow into the sea, just like a person's growth process. The sea is its endpoint. If the river stopped flowing, what would it become? A pond, a foul drain, if the river stopped flowing, it would lose its meaning of existence, and it would die. People are the same, they must go through the process of birth, growth, and death. This is a complete life. Those who can live forever, we don't know, but for ordinary people like us, birth, aging, sickness, and death are the necessary steps in the song of life."
Zhang Xiaohua asked curiously, "Why can't we live forever?"
Liu Qian said, "Because we don't know how to achieve eternal life."
