I don’t know how to spell it in Chinese Characters nor Pinyin, but I learned ‘Go Pee’ today which means 'Bullshit’. It was quite usefull this morning after I saw a street merchant type in 10 yen for a kilo of bananas, look at me, then change it to 30. “Go Pee” I say as he soon changes it back to 10 yen and grudgingly hands me my banana. Served.
