The C96 Mauser was a very popular handgun in China in the 1920s and 30s, which naturally led to a substantial number of domestically-produced copies of it. These ran the full range of quality, from dangerous to excellent. This particular example falls into the middle, appearing to be a pretty fair mechanical copy of the C96 action . However, it does exhibit classic Chinese misspelled markings - the workers who made these guns often did nor actually read English (or German), and made best-guess attempts at copying the markings on authentic firearms. The result was sometimes something like the Wauser.
