As a result, it is likely to die out soon in English, along with "stick" and "guts".[ÎÄÕÂÀ´×Ô:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ ?2o.iNy#Zw3=|`,\&m] [ÎÄÕ°æÈ¨ ½ûÖ¹×ªÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ v J}=pk/`F "}FroG] "If you've ever played 'Chinese whispers', what comes out the end is usually gibberish.
