Why do you say "tortoise omen depends on good or bad luck"?

"This is a symbol of good luck." Judging from the actual situation, tortoise divination is not commonly used in auspicious times, and it is only when encountering misfortune that tortoise omen is "combined". The purpose is, of course, to avoid evil or turn evil into good. The tortoise itself is a master at turning harm into profit. The idiom "The tortoise hides six" says: When the tortoise is in danger, it is the instinct and the spirituality of the tortoise to hide its head, tail, four legs and six limbs in its armor. People also want to learn how to "hide turtles" from their spirituality.
