Txhawm rau ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub tshuab xa khoom lub hnab ntim khoom, cov neeg ua haujlwm yuav tsum xyuas kom meej tias qhov kev sib txuas hluav taws xob muaj kev nyab xeeb thiab tag nrho cov khoom sib txuas ruaj khov - tsis muaj xoob lossis puas tsuaj - ua ntej siv. Lub cheeb tsam ib puag ncig yuav tsum tau ceev kom huv si thiab huv si ntawm cov khoom siv hluav taws xob lossis cov khoom tawg. Tsis tas li ntawd, qhov tsis xws li sealing kub thiab ceev yuav tsum tau kho raws li cov khoom tshwj xeeb thiab qhov ntev ntawm lub hnab xa khoom ua ntej lub tshuab pib.
Thaum lub sijhawm ua haujlwm, lub hnab yuav tsum tau muab tso rau hauv qhov chaw sib khi kom tsis txhob muaj qhov tawg lossis qhov tsis zoo ntawm qhov qhib, yog li ua kom muaj kev sib khi zoo. Ntxig txhais tes lossis khoom txawv teb chaws rau hauv qhov chaw txav yog txwv nruj. Yog tias muaj suab nrov txawv txav, cov txiaj ntsig tsis zoo, los yog cov khoom siv ua haujlwm tsis zoo tshwm sim, kev ua haujlwm yuav tsum nres tam sim ntawd, thiab cov neeg ua haujlwm cuam tshuam yuav tsum tau ceeb toom rau kev tshuaj xyuas thiab kho.
Thaum ua tiav kev ua haujlwm, cov khoom siv hluav taws xob yuav tsum tau muab tua tam sim; kev tu thiab tu yuav tsum tsuas yog ua tom qab lub tshuab tau nres tag nrho thiab txias. Cov dej num tsis tu ncua suav nrog kev tshem cov khib nyiab los ntawm qhov chaw sib khi, tshuaj xyuas cov khoom siv cua sov, cov txheej txheem tsav tsheb, thiab cov khoom siv hluav taws xob, thiab tswj xyuas cov ntaub ntawv khaws tseg kom paub meej tias lub tshuab tseem nyob hauv qhov kev ua haujlwm zoo thiab muab kev sib khi zoo ib yam rau lub sijhawm ntev.
