After a long time, there will be problems, because gypsum board is quite heavy, nails alone are far from enough, some gypsum board ceilings also have to be painted with white latex, and nails alone are the easiest to crack, but generally can't fall down, hehe.
Gypsum board ceilings can be nailed with 1022 yards, but it is best to always tap the screws.
If you look at the air conditioner access port, you can calculate the approximate location.
Single-layer gypsum board (or 12mm) can be used with 25mm anti-rust self-tapping screws; Double-layer gypsum board can be used with 35mm anti-rust self-tapping screws; Other cases are determined by the site.
Gypsum board ceiling with self-tapping screws is better than using wooden gun nails.
