If you go to PRC for sightseeing purpose, you can apply for a tourist L type. You should first prepare the required materials: your residence permit in Mozambique, your passport and its copy, the application form, a passport-style photo, two-way air tickets, hotel reservation, as well as other documents the consular officers consider necessary.
And then submit the application to the embassy of PRC to apply for the L type.
