(Traditional, Simplified and Kanji)
There are many heavenly kings and emperors in Asian culture, including Buddhism’s Four Heavenly Kings. The Four Heavenly Kings (風調雨順; feng1 tiao2 yu3 shun4) are gods who each watch over one of the cardinal directions (North, South, East, and West).
In modern Chinese, the phrase 天王 doesn’t always refer to heavenly kings. 天王 is now often used like the English phrases “rock star” or “superstar” to describe a famous performer or athlete.
