Four-corner method, a Common card

Power 85 (ATK + DEF): stronger than 25 % of WikiCards cards.
The facts on the card
The card carries these facts from its Wikipedia article.
- The four digits encode the shapes found in the four corners of the symbol, upper left, upper right, lower left, and lower right.
- Although this does not uniquely identify a Chinese character, it leaves only a very short list of possibilities.
- A fifth digit can be added to describe an extra part above the lower right if necessary.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Four-corner method article was read about 5,100 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 59 and blocks with 26: each hit it takes is cut by 10 %.
