平安扣也称怀古、罗汉眼，可祛邪免灾，保出入平安。

平安扣是中国的一款传统玉饰品，从外型看它圆滑变通，符合中国传统文化中的“中庸之道”，古代称之为“璧”，有养身护体之效。在现代，常为情人间互赠之物，取平安之意。和田玉平安扣现在也在有的时候用“怀古”这个名字。看到,“怀古”这个词我们联想的怀念古代含义，“怀古”这种称谓是20世纪的流行叫法，直到20世纪末，才慢慢将这个名称改为了和田玉“平安扣”，取“平安是福”的含义吧。据说，佩戴和田玉平安扣，可消灾解难,护佑佩戴者出入平安。

Hetian jade Ping'an buckle now also sometimes uses the name "nostalgia". When we see the word "nostalgia", we associate it with the meaning of nostalgia for ancient times. The appellation "nostalgia" is a popular name in the 20th century. It was not until the end of the 20th century that the name was gradually changed to Hetian jade's "Ping'an button" to take the meaning of "Ping'an is a blessing". It is said that wearing Hetian jade safety clasp can eliminate disasters and help the wearer get in and out safely.
