It regularly takes 4 working days for visa processing at Chinese Embassy in New Delhi. However, do you see the information above, if you hold oridinary Indian passport, you have to send the visa application to Chinese Visa Application Service Center rather than the Chinese Embassy in New Delhi. You'd better call the CVASC to ask the processing time. This service center will submit application to the embassy together. It hasn't right to take part in the examination and approval of visa application.
