「容成」又稱「容成公」、「榮成子」，在中國古代歷史中，既是遠古的一位帝王，又是神話傳說中的一位神仙，同時還是道教中的重要人物。有關他的身世，撲朔迷離，衆說紛紜，莫衷一是，1994 年，上博竹簡訟成氏的發現，李零教授考證為容成氏，1986年，徐州銅山縣漢王鄉發現一組漢代小祠堂，其中一塊畫像上刻有四頭神獸，榜題上的銘文是「榮成」，這組畫面的主要內容是周穆王會見西王母。這些發現，為研究榮成子的事迹提供了新鮮的考古資料。

Rong cheng is called Rong cheng gong or Rong cheng zi who is known as an ancient emperor in chinese ancient history. He is also an immortal in fairy tales and an important figure in Taoism. The legends of Rong cheng is puzzling and contradicted. The professor Liling's research on ”Rong cheng” bamboo from Shanghai Museum in 1994 discovered the existence of ”Rong cheng”. The discovery of some ancestral halls from Xuzhou Han wang in 1986 gave many new archeological materials for the study of ”Rong cheng”. One of the stones in the Han wang ancestral halls is engraved with a four-head mythical animal and the inscription of ”Rong cheng”. The major content of the pictorial stone is an interview between King Mu of Zhou and Xi Wangmu.
