I first became aware of Afghan beads crossing into China and being passed-off as "Chinese" about five to eight years ago. I believe this is a matter of recent bead movements and misrepresentation, rather than the (probably hoped-for) situation where beads changed hands in antiquity, and thus are now found in a variety of places.

for this paragraph
I have my own view ... after Tang dynasty there still was a Trade Route in north China that connect middle east with far east(northeast china today) By this route, glass ,amber and many other goods had been transported to the east... This is just why we can see here in Peking or Manchou middle east antiques today

the pics below is what I found in my hometown .In my own view they are not made by my ancestors but imported from middle east...

what do you think ?

thanks again for your frank comments
