1. Ntau- cov ntawv nplaum sib xyaw: Cov no yog ntau- cov ntawv nplaum uas cov txheej txheej tau muab sib dhos thiab sib txuas ua ke. Lawv zoo ib yam li tus kheej zoo tib yam - cov ntawv nplaum, tab sis txhua txheej tuaj yeem rov ua dua thiab rov ua dua kom pom cov ntsiab lus luam tawm.
2. Ntau- txheej folding daim ntawv lo: Cov no suav nrog caij nplooj ntoos hlav-loaded, yoj- zoo li tus, thiab accordion-style folding daim ntawv lo, nrog rau ntau- txheej cov ntawv qhia phau ntawv. Peeling tawm thawj txheej nthuav tawm cov txheej hauv qab, lossis qee zaum thawj txheej tuaj yeem qhib los ntawm ob qho kawg thiab muab tais rov qab los qhia ib daim ntawv.
3. Ntau-txheej txheej flip- nplooj ntawv sau: Tshem tawm thawj txheej nthuav tawm cov ntsiab lus zais, zoo ib yam li tig nplooj ntawv ntawm phau ntawv.
