The stories of four different eras are all touching and heart-wrenching.

1. "Riding the Wind": When the regiment leader's father was surrounded by enemies, he reluctantly chose the love of the country between a group of old, weak women and children and his own son! When the horse that had accompanied him in bloody battles for many years was seriously injured and ran towards him with the blood of his parents and children, at that moment, I couldn't help but burst into tears. If the horse could talk, I don't think I would have the heart to tell this old man. Father, the news of his son's tragic death... I just lament that the country is now safe and sound. I should be grateful to our ancestors for their hard work, so that we are lucky enough to have the comfort and peace that you and I have!

2. "Poetry": I saw my mother's greatness, wisdom, tenacity, and the light of heaven and earth! In a family, the power of a mother can turn the tide! The father in the story died due to an aerospace experiment accident. As a mother who also strives for the aerospace industry, she not only has to hide the cruel reality from her children, but also endures pain and studies technology every day. If she has not been tempered by the fire, How can one persist with a heart of steel? Mother is also the best teacher for her children. Mom is so great!

3. "Duck Prophet": witty and humorous, with a familiar flavor of old Shanghai. There is a saying in the play: The spring river water warms the duck prophet! In everything, you must be brave enough to be the first duck to dare to dive into the water. Only by bravely trying can you see the sunshine and hope!

4. "Youth": There is a passage in the play that is very impressive: it takes five thousand experiments to succeed just once! Therefore, you must be bold in doing anything, failure is inevitable, and experience is rich and precious! Hard work and self-discipline should be the norm, and the future is promising!

A movie shows four different eras. The first section demonstrates history, the second section demonstrates reform and research and development, the third section demonstrates the development of New China, and the fourth section demonstrates 21 The new era and future of the century.

The motherland is constantly making progress and getting stronger. When the people are strong, the country will be strong, when the country is strong, the people will be rich, and when the people are rich, the country will be prosperous. I am glad to be born in this great China. Now we should pay tribute to Ancestors, salute! Because of their sacrifice and dedication, we have achieved our wonderful today.
