This is Stem Lettuce, shaved and dried. It is called "Mountain Jellyfish" because it is crunchy, like jellyfish, when rehydrated. "Sound Vegetable" comes from the same crunchiness. "Tribute Vegetable" is because someone once served some to a Chinese emperor. The emperor liked it and demanded it as tribute. It is much liked in stir fries, once rehydrated.s
