The wrapping paper must be studied carefully， taking into consideration． The consideration of the glaze， the form of the wrapping paper and now the old documents were stuck together． For example， wrapping paper was stuck together in three way：
1． Documents were carefully joined by sticking about O．2 cm． of the edges

2．When wrapping paper was made， if one document was not enough for the purpose another document was joined by sticking about 2cm． of the edges together．
3． For the purpose of presentation documents were joined by sticking about lcm． of edges together．
Even the wrapping papers excavated are fragments， if the way the docum印ts were stuck together are studied， this will reveal more than just the content
