Where can I buy cheaper rubbings of ancient books?

Last year, when I went to the forest of steles in Xi 'an, I invited a tour guide to tell me that this was not the original work of Wang Xizhi, but was buried with the emperor. I seem to be surnamed Liu. The only real thing is the inscription on the glass protection inside the house, which took 26 years to get. Now many local characters are taken from this monument, such as the Chinese characters on China cigarettes! Wang Xizhi has many words that are really beautiful! Go to the forest of steles and find a tour guide.
