    Peb KauvWelded Hlisyog tsim nrog kev saib xyuas. Pib nrog hlau ib daim lossis cov paib dov, peb khoov thiab deform cov ntaub ntawv no rau voj voog. Peb mam li muab lawv tso ua ke los ua cov yeeb nkab muaj zog. Los ntawm kev siv cov kev sib tw sib txawv xws li arc vuam, peb lav tau lub zog zoo tshaj plaws thiab kav ntev ntawm peb cov khoom.
