Growth is the only way in everyone's life.
A person's life is so long, and every moment there are people meeting and walking with him; passing by and leaving. No one can know in advance what will happen next second, or who they will meet, or who will leave again. But we want to thank those who have traveled with us or left us. They have enriched our lives and promoted our growth.
The heroine Lu Meng has a metaphor for the road to growth: a moth flies into a flame. Her best friend Gu Yichun said that she was too pessimistic. If growth was like a moth flying into a flame, then everyone would end their lives at the end of their youth. Every time she heard this, Lu Meng would always say to her (because it should be said to Gu Yichun alone): "Actually, the moth doesn't know that there is a fire in front of it. It can't see the road in front of it clearly, just like we never know what may happen tomorrow. But only when it flies close to the fire, the smart ones will feel the threat of the temperature and take a detour; while the rest can only overestimate their own capabilities, but the final result will only be known after it happens."
In the article, Zhao Qiwen, who met Lu Meng, Cao Yang, who left and came back, Gu Yichun, who has always been with him, and many different people, something happened between them. Maybe it's unforgettable, or maybe it's the trivial things in life, but those are the things that prompted the growth of that group of young people.
