Trivia
The dragons puzzle in the Chinese hell is based on patterns from the famous classic Chinese book "Yi Jing". There was even an occult science based on those patterns.
The King of Hell, Yim Lau Wong (Yen Lou Wang in official Chinese), whom you encounter in the game, is indeed a popular figure of Chinese mythology. However, his origin is India, where he is called Yama or Yamaraja - the God of Death.
The Chinese signs in front of Lam's building, that you are required to memorize (in order to solve a puzzle), mean "Lam's Corporation". They are pronounced "lin shi qi ye" in official Chinese (used in PR China), but the Cantonese pronounciation is different: for example, "lin" (which means "forest") is pronounced "lam".
