The image shows a Chinese fairy tale, the “Blue Bird as a messenger”, wherein Blue Bird delivers messages for Xiwangmu (the Immortal Queen Mother). The Blue Bird is reminiscent of famsin, a novel gut-secreted hormone, which mediates communication between the intestine and other organs to promote metabolic adaptations to fasting and enhance animal survival when food is scarce. See page 273–287 by Aijun Long et al. for details.
