Paul linked to this thread recently, and I see that it is missing the following:
This is a drinking song in celebration of the brewing of Sorghum Wine (Gaoliang). It is from the movie "Red Sorghum" (thus the thread relevance) by Zhang Yimou. The lyrics are basically, "Alcohol, alcohol, alcohol, it makes you do crazy things, yea man."
Much Gaoliang today comes from Taiwan, where it is an extremely potent (100+ proof) distilled grain spirit made from a mixture of wheat and sorghum.
Proving once again that really that only reason to grow grain crops is to make alcohol.
