The inventor uses the veneer gypsum board as the ceiling board of the ceiling module, and then bends the four sides of the gypsum board toward the opposite surface of the decorative surface of the gypsum board to a preset height, so as to set the gypsum board on the opposite surface of the decorative surface of the gypsum board. The cladding keel and other connecting structures or installation structures are shielded to effectively beautify the appearance of the suspended ceiling module, thereby beautifying the appearance of the suspended ceiling system. The structure of the ceiling system is greatly simplified. By setting at least two cladding keels parallel to each other on the non-decorative surface of the gypsum board, it is only necessary to connect the cladding keels to the main keel or clips set at the top of the building, effectively reducing the construction difficulty of the ceiling system.

The modular ceiling system and its construction method provided according to the present invention will be described in detail below with reference to the accompanying drawings.
