Khoom Taw Qhia

Tooj liab tau siv los ua cov khoom dai kom zoo nkauj rau keeb kwm ntev. Vim yog cov ntaub ntawv tau yoog tau meej thiab corrosion tsis kam. Nws tseem muaj ci ci thiab tsim muaj zog. Nws yog ib qho yooj yim kom muaj xim los ntawm tus neeg sawv cev tshuaj lom neeg. Nws tau raug siv dav hauv kev siv lub qhov rooj, qhov rai, khaub ncaws, dérorations, ru tsev, phab ntsa thiab sab nraud.
