What is takyang and its rules?

It seems you're asking about "takyang". However, there's no widely recognized game or activity with that name. It's possible you're thinking of something else, or the name may be a misspelling.

To help me understand, could you provide more context? For example:

* Where did you hear the word "takyang"? (e.g., a book, a game, a region)

* What kind of activity were you thinking of? (e.g., a board game, a card game, a sport)

* Any other details you can remember? (e.g., the number of players, the goal of the game)

Once I have more information, I can try to identify the activity you're looking for and explain its rules.
