In Tibet, China, you can see colorful strips of cloth everywhere, whether it is by the riverside or in temple buildings, fluttering in the wind. Just when you are stunned, the tour guide's voice floats over: "These are colorful prayer flags. They are called prayer flags because they are printed with Buddhist scriptures. To the believers of Tibetan Buddhism, the prayer flags fluttering in the wind are like reciting the scriptures on them. The Buddhas in heaven protect the people who make and hang prayer flags. Wherever there are prayer flags, there is kindness and auspiciousness.
