These bells are rung and they say that your reputation will spread with the sound.
In the temple of the Emerald Buddha, there is the jade statue of Buddha taken by Thailand from Laos; it is now considered the heart of the Thai people. (the Emerald Buddha is not the photo above) While I was in the temple, the half dozen grandfather clocks in the room struck 12 noon, kind of an odd sound in a Buddist Temple. The temple was very quiet and full of people praying. their was, thankfully, no photography or footware allowed inside the temple.
Outside the Emerald Buddha temple, metal bells were strung all along the underside of the roof, and chimed in the wind.
We hit a really big gong at the Temple of the Dawn.
