google translate certainly did not help me with translating this article in different language wikipedia:
http://zh.wikipedia.org/zh/%E9%AD%82%E6%96%97%E7%BD%97#.E3.80.8C.E6.B0.B4.E4.B8.8B.E5.85.AB.E9.97.9C.E3.80.8D
Go down to section #7 (you can see it in table of contents).
I would appreciate it if someone translate it.
