Masha law malawng san ai ga san ni
Q1: Slot galaw da ai liner gaw screen hte maren sha re kun?
Teng sha n re. Slot galaw da ai liner gaw, jak hte galaw da ai slot ni hpe lang ai; "screen" ngu ai gaw grau nna laksan sand-hkang ai hkrang ni hpe tsun mayu ai.

Galoi mung n re. Law law hpaw ai gaw, hka lim ai lam hpe jat shangun nna, buga na n-gun hpe shayawm ya lu ai, plugging (sh) sanding galaw na matu hkam sha lam hpe jat ya lu ai. Tengman ai size hte pattern gaw formation hte bungli galaw ai masa hta madung nga ai.
