I. Cov ntaub ntawv tseem ceeb uas qhia txog kev tsim khoom
Kev npaj thiab kev teem sij hawm ntawm kev ua haujlwm ntawm kev ua haujlwm, kev ua haujlwm ntawm cov neeg ua haujlwm, kev tshuaj xyuas ntawm kev ua haujlwm zoo, thiab cov nqi ntawm cov nqi ua txhua yam raws li tus txheej txheem ntawm tus txheej txheem. Kev ua haujlwm nrog cov teeb meem hauv kev tsim khoom siv kuj tseem siv cov txheej txheem txheej txheem sib luag. Yog tias muaj kev raug mob zoo, cov luag num ntawm cov koog tsev kawm ntawv thiab cov neeg ua haujlwm yuav tsum txiav txim siab raws li cov cai tswj.
Thib ob, lub hauv paus tseem ceeb rau kev npaj ntau lawm
Thaum twg ib feem tshiab yuav raug tsim ua hauv qhov kev cob qhia, nws yog thawj zaug tsim nyog los tsim cov txheej txheem kev ua haujlwm rau ntu thiab tom qab ntawd mam npaj cov khoom raws li cov txheej txheem ntawm tus txheej txheem. Xws li: kev ntsuam xyuas ntawm cov txheej txheem tseem ceeb hauv cov txheej txheem tshiab ua cov txheej txheem; npaj cov riam uas tsim nyog, cov ntawv sau, ntsuas cov cuab yeej; cov ntaub ntawv nyoos thiab kev cog khoom lossis kev tsim khoom; yuav khoom ntawm cov khoom siv tshiab los yog cov khoom hloov qub, thiab lwm yam, yuav tsum tau nqa tawm raws li cov txheej txheem.
