Rubbings refer to rubbings made from stone or wood carvings using paper and ink and compiled into a volume.
The Dunhuang scriptures are some scriptures copied by hand in the past dynasties.
These scriptures do not have rubbings but pictures. The online Dunhuang website/idp.a4d often cannot be opened, but sometimes it can be opened. There are a large number of pictures for viewing.
In addition, you can also see some scriptures by searching for "Dunhuang Scriptures" on Baidu Pictures.
