Mahse, professional kan nih angin hei hi kan hmachhawn nghal tur a ni: pawn lama LED display hlawhtlinna leh hlawhchhamna 70% chu installation awmna hmun environmental assessment-ah a innghat a ni. Nikum khan commercial plaza design ka siam lai khan client chuan main building sir lamah 8{5}}meter-a sang screen dah a tum tlat a. On-site survey an neihah chuan he hmun hi kum khata thli tleh chak zawng chu level 7 a ni a, subway vent bulah a awm tih hmuhchhuah a ni.
