Peb ntseeg tias qhov zoo yog peb lub neej. Peb ib txwm tuav thawj chav kawm zoo hauv kev ua lag luam thiab tau txais txiaj ntsig los ntawm peb cov neeg siv khoom. 90 feem pua ntawm peb cov khoom raug xa tawm mus rau Asmeskas, Europe, Thaib, Nyab Laj thiab lwm yam.
Yog li, rau qhov kev xeem xyaum, txhua zaus peb hais kom sim nws qhov kev ua tau zoo.
Rau HSSM2 Tin coated laum khoom, 4.1mm loj, tag nrho xyaum txog 400 qhov. peb ntseeg tias qhov zoo yog thawj.
Txhua qhov laum me me yuav tsum muaj qhov zoo. Feem ntau peb ua qhov kev xeem no, thiab qhia cov ntawv xeem rau peb cov neeg siv khoom. yog tias pom qee qhov teeb meem, peb yuav tham nrog peb cov neeg ua haujlwm kev cob qhia thiab txhim kho kev xyaum ua haujlwm.
Ncaj HSS laum cov khoom ua tau zoo kuaj xyuas
