It's amazing to see how much progress my country has made. Let me tell you all about it!First, let's talk about China's economy. Just a few decades ago, China was a relatively poor country. But thanks to smart policies and extremely hard work, China's economy has grown enormously! China now has the second largest economy in thewhole world after the United States. Tons of big companies are based in China like Alibaba, Tencent, and Huawei. Chinese people have much more money to spend on cool things than before.China's cities have transformed at a mind-blowing rate too. When my parents were young, most people lived in small villages and towns. But now, China has massive, futuristic megacities with skyscrapers, subways, and every modern amenity you can imagine!
