The Shang dynasty, also known as the Yin dynasty, was a Chinese royal dynasty that ruled in the Yellow River valley during the second millennium BC, traditionally succeeding the Xia dynasty and followed by the Western Zhou dynasty. The classic account of the Shang comes from texts such as the Book of Documents, Bamboo Annals and Records of the Grand Historian. Modern scholarship dates the dynasty between the 16th and 11th centuries BC, with more agreement surrounding the end date than beginning date.

Written Chinese is a writing system that uses Chinese characters and other symbols to represent the Chinese languages. Chinese characters do not directly represent pronunciation, unlike letters in an alphabet or syllabograms in a syllabary. Rather, the writing system is morphosyllabic: characters are one spoken syllable in length, but generally correspond to morphemes in the language, which may either be independent words, or part of a polysyllabic word. Most characters are constructed from smaller components that may reflect the character's meaning or pronunciation. Literacy requires the memorization of thousands of characters; college-educated Chinese speakers know approximately 4,000. This has led in part to the adoption of complementary transliteration systems as a means of representing the pronunciation of Chinese.
