Yuav ua li cas txiav txim qhov zoo ntawm ib tug khiav saw?Tsuas yog saib ntawm qhov chaw tsis txhim khu kev qha.Cov txheej txheem ntau lawm thiab kev tshuaj xyuas nruj yog qhov lav rau kev tsim cov khoom lag luam zoo.
GT ua rau cov txheej txheem ntau lawm pob tshab, tso cai rau cov neeg siv khoom nkag siab txog tag nrho cov txheej txheem tsim khoom ntawm cov kab khiav, kom cov neeg siv khoom siv tau yooj yim.Tau dhau los ua tus neeg muab khoom lag luam txhim khu kev qha rau cov neeg siv khoom
