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/ pxP=*[he{_sLS9L] [ÎÄÕ°æÈ¨ ½ûÖ¹×ªÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ ;vEC#Tx`Dy0=x}4XNFroG] "If you've ever played 'Chinese whispers', what comes out the end is usually gibberish.
