The Taiwan blue magpie, also called the Taiwan magpie, Formosan blue magpie, or the "long-tailed mountain lady", is a bird species in the crow family. It is endemic to Taiwan.

Yu Shan or Yushan, also known as Mount Jade, Jade Mountain, Tongku Saveq or Mount Niitaka during Japanese rule, is the highest mountain in Taiwan at 3,952 m (12,966 ft) above sea level, giving Taiwan the 4th-highest maximum elevation of any island in the world. It is the highest point in the western Pacific region outside of the Kamchatka Peninsula. Yushan and its surrounding mountains belong to the Yushan Range. The area was once in the ocean; it rose to its current height because of the Eurasian Plate's movement over the Philippine Sea Plate. Yushan is ranked 40th by topographic isolation.
