obscures the other line. The design is also described as a "pair of fishes nestling head to tail against each other". The Soyombo symbol of Mongolia may be prior to 1686. It combines several abstract shapes, including a Taiji symbol illustrating the mutual complement of man and woman. In socialist times, it was alternatively interpreted as two fish symbolizing vigilance, because fish never close their eyes. The modern symbol has also been widely used in martial arts, particularly t'ai chi ch'uan (Taijiquan), and Jeet Kune Do, since the 1970s. In this context, it is generally used to represent the interplay between hard and soft techniques. The dots in the modern "yin-yang symbol" have been given the additional interpretation of "intense interaction" between the complementary principles, i.e. a flux or flow to achieve harmony and balance. Similar symbols Similarities can be seen in Neolithic–Eneolithic era Cucuteni–Trypillia culture on the territory of current Ukraine and Romania.

Unlike the Chinese symbol, the Celtic yin-yang lack the element of mutual penetration, and the two halves are not always portrayed in different colors. Comparable designs are also found in Etruscan art. In computing Unicode features the he tu symbol in the Miscellaneous Symbols block, at code point .
