China’s Great Development
In recent years, China has witnessed remarkable development and changes, which have significantly influenced every aspect of people’s lives.
In technology, innovations like CCTV’s Yangko robots and AI such as DeepSeek, which surprise the world, show amazing progress. Culturally, movies like Ne Zha 2, which broke global box office records, spread Chinese stories worldwide. Economically, rising living standards bring more opportunities. These changes make daily life more convenient and fill us with pride.
As teenagers, I believe that we should study hard to master skills and take responsibility for our nation’s future. By staying curious and creative, we can contribute to China’s ongoing miracles!
