边工作边听Louis Armstrong 的歌，忽然想起今年夏天和爸爸妈妈去大峡谷，我们坐在五人的直升飞机里，带着耳机，爸爸妈妈就在我的身边，直升机起飞，一路接近大峡谷，忽然平原绿地变成了地球的崩裂，巨大的坑古在我们面前，巨大无比，像autobots里面的一样，一个声音会突然说，calling all autobots，然后巨大的机器人会从山崖后面现身领命。
那时候，耳机里放的是What a wonderful world. 真是特别贴切，特别感动，就是那样的，奇妙的世界。
At the Historical Fair, New Berlin, WI, the blacksmith quizzed his audience about the functions of the “ding ding” sound coming off from the anvil as the hammer hits on iron.
Nobody gets the right answer. Interesting. It’s—-advertising!!
You’d need to pay extra for the type of anvil that makes loud, crisp ding ding sound. Anvils used to sound just dull. Someone then invented a type of material for anvils that can create the ding ding sound. And it sold like hot cake. The dull-sounding anvils went out of business.
Now we are stuck with the anvil that is very loud and deafening. It’s a primitive form of advertising. Blacksmiths needed to be known they are open for business. People seek them out by their sound. Is this the same as 弹棉花？货郎的拨浪鼓obviously is advertising
