What are the four languages behind Oracle Bone Inscriptions?

Bronze inscriptions, seal script, official script, regular script.

1. Bronze inscriptions in Yin, Shang and Zhou Dynasties, also known as Zhong Dingwen, are a calligraphy name of Chinese characters.

2. The seal script is a general term for the big seal script and the small seal script. Big seal script refers to inscriptions on bronze inscriptions, bronzes and six-country scripts, which retain the obvious characteristics of ancient hieroglyphics.

3. Lishu is a common solemn font in Chinese characters, with a slightly flat writing effect, long horizontal painting and short straight painting, and pays attention to "swallow tail of silkworm head" and "twists and turns".

4. Although China's regular script sprouted in the Eastern Han Dynasty, the truly literate regular script appeared in the Wei and Jin Dynasties. Regular script changed from folk germination to calligraphy orthodoxy, and was widely studied by scholars at that time as a fashion. This is also the most widely used Chinese character.
