Orаcle Bоnes were the shоulder blаdes оf oxen or the flаt underside of the turtle's shell which were used in the Shang Dynasty for divination (seeking knowledge of the future). The symbols carved on the bones eventually became words and developed into a recognizable Chinese written language. Oracle bones are crucial for studying early Chinese history, language, and culture, with over 200,000 fragments discovered, containing some of the earliest examples of the Chinese alphabet. Divination using Oracle Bones was only performed by specialist “diviners,” who were often priests or advisors to the King. People who wanted to ask about the future would visit these diviners and pay them to get answers from the bones. Priests inscribed questions, heated the bones to create cracks, and interpreted these cracks as answers from ancestors or spirits. Fortune-telling during the Shang Dynasty was considered an important resource in making decisions, and these 'psychics' were consulted by everyone from the farmer to the king. The fortune-tellers were thought to be in touch with the spirit world of the ancestors who lived with the gods and knew the future. QUESTIONS: 1. What information about the Shang Dynasty can experts get from studying Oracle Bones? 2. What types of questions do you think people wanted to know about the future? Your answer must be in your own words and must be supported by specific information from the reading. Your answer must be a minimum of 75 words.
