2006 年 I've been to East and Southeast China (Shanghai, Jiangsu, Zhejiang, Anhui). In my travel report I diskussed if the numbers 4, 10, 7 and 1 would become all the same. It took some time to tune in the local dialect, although I had been to Shanghai before. First only '10' (shi2) sounded as '4" (si4), next someone demanded 'si4 kuai4' (4 Y RMB) in exchange for some bottles of water. Givimg him 10 he returned 3. That means it cost 7 (qi1). The amout was OK, but I thought '1' (yi1) would be next. Poor '1'. Is this the future? Will wi all end saying 'Si si si, si si si si si. Si si?', whatever it might mean?
