Cov cuab yeej tso tawm sai yog ib qho ntxiv uas tso cai rau kev ua haujlwm yooj yim thiab ua haujlwm tau zoo. Nrog rau cov txheej txheem yooj yim, cov neeg siv tuaj yeem tso tawm cov hlau nplaum ceev ceev ntawm cov khoom khaws cia, ua kom yooj yim sib sau thiab nrawm yam tsis muaj teeb meem lossis tsis yooj yim.
Cov cuab yeej yog tsim los siv cov khoom siv ruaj khov, ua kom nws lub neej ntev thiab tsis kam hnav thiab tsim kua muag. Qhov no ua rau nws haum rau kev siv ntau zaus hauv kev lag luam, kev tsim kho, lossis txawm tias siv hauv tsev.
Cov cuab yeej sib nqus hlau nplaum yog lub teeb yuag thiab txav tau yooj yim, ua rau nws yooj yim rau nqa thiab khaws cia. Nws cov qauv tsim qauv kuj tso cai rau kev yooj yim maneuvering thiab nkag mus rau qhov nyuaj-rau-mus txog qhov twg cov khoom siv hlau yuav poob los yog ua tsis tau.
Cov cuab yeej no yog qhov tseem ceeb ntxiv rau txhua lub cuab yeej lossis ib puag ncig ua haujlwm uas cov khoom siv hlau yuav tsum tau sib sau los yog tshem tawm kom zoo. Nws cov hlau nplaum muaj zog, cov cuab yeej tso tawm sai, ua haujlwm ntev, thiab txav tau yooj yim ua rau nws muaj peev xwm txhim khu kev qha thiab tseem ceeb rau ntau yam haujlwm thiab kev siv.
