In 1947 Professor Lien-sheng Yang of Harvard University proposed that the design of TLV mirrors was related to an ancient Chinese boardgame called liubo, which was played on a square board with the same markings as seen on this type of mirror. Further evidence was presented in an additional note in 1952. An ancient rubbing of a first century Chinese bronze mirror discovered in the National Museum of China in 1980s further confirms it.
