Super bird's nest is expensive. Super bird's nest has good quality, complete and full cup shape and white and glittering color. This is the first bird's nest built in Jin Siyan, which is difficult to pick and produces less. The silk strips of Baiyan Cup are thin, smooth and not fire-resistant. It needs to be soaked and stewed for many times before eating, so the price is lower than that of Super Bird's Nest.
