Bei Wu Long in Cantonese means to make a big mistake.
- What are the Chinese characters for this?
- Is there a story for this?
I'm pretty sure that the " Bei Wu Long" is "摆乌龙". "乌龙" in Cantonese sounds like "own goal" in English. You know own goal is a big mistake, right？
It is a long story. According to this website, is is original from a folk tale in Canton. Once upon a time, there was a drought. People prayed to the "青龙"(Green Dragon) because it can bring rain. However, at last it was the "乌龙"( Black Dragon) who bring disaster that answered to them. The situation became worse.
Then in 1960s, journalist in Hongkong use "乌龙" to describe the "own goal" in soccer game because the "乌龙" sound similar in Cantonese to "own goal".
The Chinese character is : 摆乌龙
There was a heavy drought in Guangdong, people prayed the Thanh Long to give people rain, but Wu long came instead of Thanh Long , and it brought big disaster to people.
So 摆乌龙 means to make a big mistake.

There's no explanation for it (except that it does state "accidentally score against one's own team").
