Valve cov ntsiab lus! Nov yog txhua yam koj tsis paub txog lub kaum sab xis
Yog tias lub kaum sab xis ntws tawm, thiab pom tias cov tub ntxhais ntawm lub kaum sab xis tawg, nws tuaj yeem hloov lub kaum sab xis xwb. Yog tias pom tias qhov xau ntawm lub kaum sab xis yog nyob ntawm qhov sib cuam tshuam, tsuas yog rov qhwv cov khoom siv raw khoom siv thiab nruj nws. Nyob rau hauv lub neej tiag tiag, daim duab peb sab ntawm lub rhaub dej tau tawg sai li sai tau thaum lub tsev tshiab ntawm qee tus tswv tiav lawm, uas ua rau cov kav dej xau thiab dej nyab hauv pem teb, TV txee, wardrobe, thiab lwm yam. Qhov no tshwm sim, feem ntau yog vim qhov zoo ntawm Lub kaum sab xis valve tsis yog tshwm sim los ntawm. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm kev kho kom zoo nkauj hauv tsev, peb yuav tsum tau them sai sai rau qhov kev xaiv ntawm zoo zoo Lub kaum sab xis valve tsis txhob yuav penny txawj ntse thiab phaus ruam.
