In ancient times, ornaments made of pearls and jade were mostly used as necklaces. At first, the wreath was a decoration between the necks of ancient Indian Buddha statues, and later it was introduced to China with Buddhism. In the Tang dynasty, it was imitated and improved by women who love beauty and seek novelty, and became a necklace. Its shape is relatively large and it is the most luxurious necklace.
The production materials of "wreath" are "the crown of all treasures, the wreath of eight treasures" in Vimalakīrti Classic; According to the Lotus Sutra, all kinds of flowers are made of "gold, silver, glass, tortoise shell, agate, pearls (that is, pearls) and seven treasures of roses (there are many versions of the interpretation of seven treasures). It can be seen that wreaths should be made of all the treasures in the world, which means" boundless light ". In addition, there is the meaning of beautiful jade.
