Qauv Ua Haujlwm: Xyuas kom cov fuse sib txuam muaj cov ntawv pov thawj uas muaj cov ntawv pov thawj xws li iso {}} {1} {} rau kev nyab xeeb hauv tsheb.
Cov txheej txheem xaiv siv tau cuam tshuam:
Txiav txim siab cov txheej txheem hluav taws xob thiab xav tau .
Kev tshuaj xyuas qhov siab tshaj plaws yog cov tsis ntseeg .
Xyuas qhov chaw teeb tsa thiab kev sib txuas hom .
Xyuas ua raws li kev lag luam cov qauv kev lag luam .
Suav nrog kev sib piv ntawm cov qauv fuse fuse cov thawj coj tuaj yeem pab cuam tshuam hauv kev sib txuam fuse cov kev pab cuam los thov thov.
