belief that is not based on human reason or scientific knowledge, but is connected with old ideas about magic, etc.

According to superstition, if you walk under a ladder it brings you bad luck. 按照迷信的说法，从梯子下走过会带来厄运。

I don't believe in the old superstition that the number 13 is unlucky. 我不相信数字13不吉利这样的旧迷信思想。
