Guang Zhi 70XPII Edition does not provide the function of exporting books and materials (you can export the book inventory table or indirectly export books and materials, but it is incomplete. For example, some books have established materials, but they have never been in business and have no inventory, so the materials of this variety will not be exported).

If you just want to adjust the book inventory correctly, you can use Guang Zhi's inventory function. Through inventory, you can adjust the inventory of all sold varieties. For unsold varieties, the computer will think that these varieties have been sold out and will automatically empty their inventory.
