2. South is a word of orientation, that is, facing the sun in the morning, and the right hand side is opposite to "North". Extension refers to the southern region or country. It also refers to the music of ancient southern minorities.
3. Chen's original meaning is that the sting is ready to move when it wakes up, which means vibration (that is, the so-called "shock" in Shuo Wen Jie Zi). One said that the original intention was a farm tool made of clams. Guo Moruo believes that astrology is closely related to farming, so "Chen" refers to the sun, the moon and the stars, or to Beichen and the stars, or to the heart of one of the 28 places, or to the intersection and date of the sun and the moon.
4. Chinese characters: Chinese characters are the recording symbols of Chinese and are also used in Japanese, Korean and other languages. Different from English, Russian, Hindi and Arabic, Chinese characters are typical linguistic signs. Different from monosyllabic or polysyllabic meanings of phonetic words, Chinese characters generally have monosyllabic meanings.
5. The earliest existing Chinese character is Oracle Bone Inscriptions in Shang Dynasty, about 1300 BC. Later, bronze inscriptions appeared, which evolved into the seal script of the Western Zhou Dynasty, and then the seal script of the Qin Dynasty unified six languages. Official script appeared at the end of Qin Dynasty, cursive script appeared in Western Han Dynasty, and regular script and running script appeared in Eastern Han Dynasty. The strokes of Oracle Bone Inscriptions, Jinwen and Zhuanshu are tactfully continuous. When the strokes of Lishu become horizontal and vertical, they become pure square characters, which are convenient for writing and become the dividing line between ancient and modern Chinese characters.
6. Chinese characters have a history of more than 6,000 years, and they are the longest-used unbroken characters in the world. Chinese characters are the only words that have survived to this day. The derivatives of Chinese characters, such as Vietnamese, Xixia, Jurchen and Qidan, have died out, while Japanese, Korean and Korean only partially retain Chinese characters. Modern Chinese characters are divided into traditional characters and simplified characters.
