The fortune teller said that I was a lotus beside Guanyin Bodhisattva, and I was going to die at the age of 29.

Don't believe what he said, it's sheer nonsense!

Buddhism believes that avalokitesvara is one of the three saints in the western paradise, and the lotus flowers around avalokitesvara are all ten dead beings in the paradise, all of whom are buddhas who never retreat to become buddhas. If you come to this world, you must be a Buddha who wants to come back, and you will never die in the fog.

So you don't have to worry, it's just a lie.
