文字 (Wénzì) refers to written characters used in the Chinese language. These characters represent words or ideas and are an essential part of Chinese communication. Each character has its own meaning and can be combined with others to form phrases and sentences. The development of 文字 dates back thousands of years, with the earliest forms found in oracle bones from the Shang dynasty. Over time, the characters have evolved, leading to various styles such as 楷书 (Kǎishū) and 行书 (Xíngshū). Today, 文字 remains a vital aspect of Chinese culture and identity.
