Zhuang Zhou (/dʒuˈɑːŋ ˈdʒoʊ/), commonly known as Zhuangzi (/ˈdʒwɑːŋˈdzʌ/; Chinese: 莊子; literally “Master Zhuang”; also rendered in the Wade–Giles romanization as Chuang Tzu), was an influential Chinese philosopher who lived around the 4th century BCE during the Warring States period, a period of great development in Chinese philosophy, the Hundred Schools of Thought. He is credited with writing—in part or in whole—a work known by his name, the Zhuangzi, which is one of two foundational texts of Taoism, alongside the Tao Te Ching.

Beta Draconis (β Draconis, abbreviated Beta Dra, β Dra) is a binary star system and the third-brightest star in the northern circumpolar constellation of Draco. The two components are designated Beta Draconis A (officially named Rastaban /ˈræstəbæn/, “head to sole of foot”, the traditional name of the system) and B respectively. With a combined apparent visual magnitude of 2.79, it is bright enough to be easily seen with the naked eye. Based upon parallax measurements from the Hipparcos astrometry satellite, it lies at a distance of about 380 light-years (120 parsecs) from the Sun. The system is drifting closer with a radial velocity of −21 km/s.
