First, prepare the relevant documents: your passport and its copy, the application form, a passport-style photo, valid visa for Maldives, round trip air tickets, hotel reservation, bank statement, and an invitation letter from Chinese tourism bureau as well as other documents the consular officers consider necessary.
Next, go to the embassy of China to submit the application.
