mah jong symbolism
As a mah jong player and collector, I noticed some things in Lust, Caution that I thought I should share.
1.) There are two mah jong sets in this movie, both made of bone dovetailed to bamboo. The more valuable type of this set has a thick bone layer in proportion to the bamboo. In the first scene of the movie (at the end of the story, as it turns out), you'll see they're playing with a valuable set -- the bone layer is quite thick. At an earlier point in the story (when the Yees would have been less wealthy) they play with a less valuable set. Look for the scene that begins with one of the women complaining that the family has just lost their cook. You'll see that the bone layer on the mah jong tiles they're playing with is much thinner.
2.) One of the honor tiles in a mah jong set has the character "zhong". It's drawn in red on the tile. "Zhong" means "center" and is the first character in the word for "China" ("center kingdom"). In the first mah jong scene, one player (Ma Tai Tai?) gets all four ("kai gang") of these tiles, turns them face down, and draws another tile. In the second mah jong game, one of the women remarks that another's husband must be about to get a promotion. Yee Tai Tai then draws a "zhong" tile, turns it over for everyone to see, and throws up her hands and lets out an exaggerated feminine scream. I think the idea here is that drawing the tile that represents China is a good omen for the husband's promotion to a high place in government.
3.) In the one mah jong game where Mr. Yee plays, notice that after Wong Chia Chi wins a hand, Mr. Yee pulls out a drawer of the table which contains little bone sticks. These sticks are counters that are used like poker chips, to keep track of a player's winnings. Mr. Yee will award counters to Wong Chia Chi, depending on the value of her winning hand.
4.) In China, mah jong is usually played for money. All of the usual gambling metaphors apply -- "she played for her life and lost", etc. I think the last line of the movie is brilliant -- "keep playing".
