Puas faib khoom siv rau kev faib?
Lub faib khoom tsis siv rau kev faib tib yam txij li nws ua nrog kev sib tw, tab sis lub tswv yim ntawm kev faib lossis "sib cais" tuaj yeem siv los faib. Puas kev faib raug kaw raws li kev faib khoom? Raws li cov cuab yeej no, cov khoom ntawm cov lej lossis qhov sib txawv ntawm tus lej yog sib npaug rau cov lej lossis qhov sib txawv ntawm cov khoom.
