In Chinese mythology, Lei Gong (Chinese:雷公; pinyin:léi gōng; Wade–Giles:lei2 kung1; literally: "Lord of Thunder") or Lei Shen (Chinese:雷神; pinyin:léi shén; literally: "God of Thunder"), is the Chinese traditional religious and Taoist deity. In Taoism, when so ordered by heaven, Lei Gong punishes both earthly mortals guilty of secret crimes and evil spirits who have used their knowledge of Taoism to harm human beings. He carries a drum and mallet to produce thunder, and a chisel to punish evildoers. Lei Gong rides a chariot driven by a young boy named A Xiang.
