Only a few miles across the water from mainland China, the Beishan Broadcasting Wall (北山播音牆) in non-communist-controlled Kinmen County:
. . . stands on a cliff right by the sea. The concrete wall boasts 48 speakers, each with a reported range of 25km, that used to crank out propaganda like 'Our steamed buns are bigger than your pillows!' to the communists. These days, the speakers prefer the more mellow numbers of the late Teresa Tang, Taiwan’s best-loved songbird.Unfortunately, they didn't turn on the three-stories of speakers to broadcast Teresa Teng's message and songs at a non-deafening volume during my visit to the wall.
The following two minute video offers additional information about the structure's capabilities, perspective on its size, and a translation of Teng's message:
Another video offers a purer form of Teng's message and singing without anyone speaking over it:
On the side, I have yet to see a steamed bun the size of a pillow.
