The Chinese writing system is an unique phenomenon in the modern world of alphabet scripts. Instead of a few dozen letters, it has developed thousands of complex signs or "characters" that represent morphemes and words. Even related writing systems such as Japanese and Korean, while sharing many of the same characters, can fully function as purely phonetic scripts. And while it is not the only living logographic writing system in the modern world, it is the only one serving as the primary writing system for hundreds of millions of people.

The first recognizable form of Chinese writing dates from 3,500 years ago, but many argue that its origins lie much deeper in the past. Regardless of its actual age, Chinese has evolved substantially over time yet has retained its ancient core, making it one of the longest continuously used writing system in the world.
