The LawBod's legal history collection policy is concentrated on works on the Anglo-American or common law legal tradition. However we are not without some works which might support your interest. SOLO searches will reveal if other parts of the Bodleian such as the Chinese Studies Library can further assist.
In the Bodleian Law Library, books with a shelf mark starting China can be found on Level 1, one floor beneath the entrance level. There are seats for readers on that floor too.
