The historical record of Wan Ziwen.

Ci Hai called Wan "an ancient spell, amulet or religious symbol", which appeared in the history of ancient India, Persia, Greece and other countries, and was later adopted by some ancient religions, such as Brahmanism and Buddhism. Later, it developed into a symbol of firmness, eternity, evil spirits and auspiciousness, which is an eternal auspicious symbol. "Yan" originated from prehistoric culture. About 5000 BC, the "swastika used by the Nazis" was found on pottery in Mesopotamia, West Asia. After entering the Bronze Age, swastika was also very popular in Europe. As a decorative symbol, it is also very common in early Christian art and Byzantine art. Previous studies once thought that the swastika was introduced to China through Buddhism, but in fact, the swastika in China can be traced back to Majiayao culture in the late Neolithic age about 4,000 years ago, and Buddhism was introduced to China in the Eastern Han Dynasty. However, with the introduction of Buddhism, the "swastika" symbol became more popular and used in China. Neolithic pottery, bronze hooks of Shu State in Cuba, bronze wares of Tang Dynasty, brocade of Qing Dynasty and hollowed-out doors and windows can be seen everywhere. However, the "swastika" patterns used on these objects are mostly auspicious patterns, which once had a strong religious meaning and gradually lost their original meaning, while the aesthetic elements became stronger and stronger, and gradually evolved into the aesthetic objects of national traditions.
