What position does palindrome occupy in China's typical geometric traditional patterns?

Palindrome is one of the typical geometric traditional patterns in China, and its orderly and rational turn adds a delicate and solemn stroke to the history of Chinese traditional pattern art. Palindrome originated from the vortex pattern on pottery unearthed from Majiayao cultural site in Neolithic age. The palindromes on Shang and Zhou bronzes laid the most mainstream aesthetic style of that era. The palindromes in the Western Zhou Dynasty and the Warring States Period developed a new model. The palindromes in Song Dynasty reflected the rational regression psychology of the society at that time.
