Today, I saw Penglai Beach in China, dreaming.
This episode is about a professor named Jin Yugan who was attracted by the overlapping rocks on Penglai Beach when he went to Penglai Beach. Since then, he has been here countless times. The rocks on Penglai beach recorded the Permian extinction event more than 200 million years ago, and Professor Jin Yugan cracked it. Professor Jin Yugan has spent more than twenty years studying these rocks. Several times, he was ill. However, this did not kill his will. Although he was ill, he went to inspect them. Sure enough, many things have happened and his research has finally achieved great results-he has developed a "golden nail" in Penglai Beach, and since then, the name of China people has appeared in the study of geological period. The so-called "golden nail" is to mark the time point of geological period with the time point when organisms evolved from one species to another.
We should learn from Professor Jin's persistence, perseverance, courage to explore and dedication to science.
