In China and even in Asia, almost every family believes in avalokitesvara. It has been like this for thousands of years, and our wise ancestors will not talk nonsense.
According to Buddhist scriptures, there are only two kinds of people who want to see Guanyin Bodhisattva. One, those who have great wealth will meet Guanyin. Second, practitioners can practice to the sacred position above Sudoku, or meet Guanyin Bodhisattva in the bliss of Amitabha when they are dying.
Even if you can't see it, the feeling of avalokitesvara is really real. If a person encounters an extremely dangerous moment, as long as he reads Guanyin Bodhisattva for help, he can get the induction of the Bodhisattva. This is something that countless people have experienced, and it is also the reason why everyone believes in Guanyin Bodhisattva so widely.
