Regarding the statement of Lolalei, the meaning of "Lolelei" is actually the meaning of the reef. There is a strange natural phenomenon in the Luoleilai Mountain Rock, which is the 7th echo. Before the 19th century, there was a small waterfall on the Luoleilai reef. The water flow was rushing, and the echo effect formed was a whispering voice from the reef. Before the real reason was found, people thought that it was living. The dwarfs in the reef caves are whispering. Nowadays, due to the surrounding traffic noise, the echo effect has not been heard. There is a legend that a woman named Luo Leilai is sitting on the Luoleilai reef. She uses a golden wooden comb to comb her long blond hair. The crew of the Rhine River was Her beautiful singing was attracted because she did not notice the dangerous turbulence and the steep reef, and unfortunately sank with the ship. No matter which one, what we can see now is a statue. There are no more beautiful songs, or whispers of streams.
