The first layer (from "autumn water to" to "take the beauty of the world as your own") describes the grandeur of the Yellow River and Hebo's complacency.

On the second floor (from Going with the Wave to My Parents Laughing at the Generous Family), it is better to write Hebo's sigh after seeing the sea.

Life is a unique phenomenon of all kinds of creatures on the earth. Life is the most precious wealth in nature, and the world is wonderful and moving because of its existence.

Important educational significance:

On May 12, 2008, Sichuan Wenchuan Earthquake, more than 2,200 students and 100 teachers from Sangzao Middle School in Anxian County all rushed to the playground from different teaching buildings and different classrooms, and stood well in the class as an organizational unit. It took 96 seconds, and no one was killed or injured, creating a great miracle. 1On September 20th, 995, an earthquake of magnitude 5.2 occurred in Cangshan County, Shandong Province. Although the earthquake damage did not cause direct casualties, students' psychological panic during the earthquake caused them to jump off buildings, get crowded and trample, resulting in 320 injuries. Therefore, strengthening earthquake safety education for primary and secondary school students has become an important link in the propaganda of earthquake prevention and disaster reduction.
