People in South China speak a different type of Chinese than people in the North. They call it "Cantonese". Actually, most of the Chinese immigrants living in New York also speak Cantonese or other southern Chinese languages. Cantonese is so different from northern Chinese languages that a person from the south and a person from the north cannot understand each other. Amazingly, they still use the same language system to read, so everyone can read the same newspaper, even if it sounds different when they say the words out loud.
Chinese people use money called the Renminbi (ren-min-bee), which means "People's Money" in Chinese. The bills are bright and multicolored, but almost no one ever uses them. Instead, people use their phones to automatically pay for everything by just clicking a button. They don't even use credit cards! This is an example of how China has become very technologically advanced.
