So the rules of modern XiangQi seem to be more ancient than the rules of modern Western Chess, since Western Chess is the result of the great reform of the Arab Chess "Shatranj" round about 500 years ago, whereas the latest change of rules in XiangQi already date back to 840 A.D., as we have just heard from you. And not just that, Professor Li. You go even further. Whilst the majority of historians keep telling us that chess was invented in India sometimes during 400 and 500 A.D., you are convinced of a different origin of chess – roughly 2200 year ago. In your "Syllabus"-series on XiangQi you claim that XiangQi was invented in 203 B.C. by the commander-in-chief of the Kingdom of Han, the general Hán Xin. Do you have any proof for that?According to Professor Li, the date of the invention of XiangQi is 203 B.C.; so proto-chess, meaning: an early version of chess, originated in China. Xiangqi is a Chinese game in a family of strategic board games of which Western chess and Japanese shogi are also members. The Chinese name is literally translatable as either "elephant chess" or "symbolic chess" but is commonly called Chinese chess in the West. The ancestry of Xiangqi is disputed with some historians contending that it originated from Liubo and others stating that it is a relative of the 6th century Indian game of chaturanga. It is one of the most popular board games of the chaturanga family in the world, especially in Asia. Distinctive features of xiangqi include the unique movement of the pao piece, a rule prohibiting the generals from facing each other directly, and the river and palace board features, which restrict the movement of some pieces.
