Daim ntawv thov nta
Ntawm kev muag khoom muaj feem ntau yog qib qis lossis nruab nrab ntawm GOI nplej zom. Yog li no, koj tuaj yeem hnov ntau qhov kev tsis txaus siab uas lapping nrog muab tshuaj txhuam tsis ua haujlwm. Qhov no yog vim hais tias qhov kev txiav txim ntawm daim ntawv thov ntawm ntau yam tsis ua raws. Thiab tsis yog txhua tus neeg muag khoom tuaj yeem piav qhia cov nplej zom nws tau muag. Nws tshwm sim hais tias tom qab sib tsoo nrog abrasive, koj tam sim ntawd xav kom tau txais daim iav ci.
