What does Chinese character 20 mean?

The Chinese character 20 means number, which means twenty when pronounced as niàn n. The earliest hieroglyphs were found in Oracle Bone Inscriptions in Shang Dynasty. Like the other 20 numbers, they are: 30, 30, Wei, Yuan, Jin, Wei, Er, Di. China's culture is extensive and profound, with one word and one culture. "Twenty" can be seen in Confucius's "Peach Blossom Fans Drive the Society" in the Qing Dynasty: "Look at the Thirteen Classics, the Twenty-first History, the Nine Schools and Three Religions, a hundred schools of thought contend, bad essays, novels and stories, full of boxes and shelves, and high and low columns on the fourth floor."

Oracle Bone Inscriptions is an ancient script in China, also known as Wen Qi, Oracle Bone Inscriptions, Yin Ruins or tortoise shell and animal bones. It is the earliest mature Chinese character we can see, mainly referring to the characters carved on tortoise shells or animal bones by the royal family in the late Shang Dynasty in China. It is the earliest known written carrier of Shang Dynasty in China and East Asia.

It was first discovered by villagers in Xiaotun Village, Anyang, Henan Province. They didn't know it was an ancient relic at that time. It is only used as a medicinal "keel" to treat all diseases. Many tortoise shells and animal bones engraved with Oracle Bone Inscriptions were ground into powder, wasting many extremely precious cultural relics.

Later, in the 25th year of Guangxu (1899), Wang, an official and epigraphist in the late Qing Dynasty, discovered the location of Oracle Bone Inscriptions from the Oracle bones unearthed in Anyang, Henan. Over the past century, more than 54,600 pieces of Oracle bones/KLOC-0 have been unearthed in the local area through archaeological excavations.
