1. Qhov twg yuav tsum muaj qhov hnyav, tab sis ntoo thiab lwm lub sijhawm nyuaj rau kom tau raws li qhov xav tau ntawm kev siv.
2. Kev siv ib puag ncig uas yuav tsum tau txo qhov hnyav thiab qhov nruab nrab thiab thauj khoom qis, xws li kev siv cov khoom yas hauv tsheb, dav hlau, nkoj thiab nkoj loj yog qhov tseem ceeb.
3. Ntau yam khoom siv hauv cov khoom nruab nrab thiab qis, xws li lub zog thiab cov kabmob uas siv dav hauv kev lag luam tshuab.
4. Cov khoom lag luam nrog cov duab sib txawv muaj cov yam ntxwv ntawm kev ua haujlwm siab, raug thiab ua qauv sai ntawm cov yas rau cov khoom lag luam, xws li kev tsim cov tsev nyob hauv TV.
