Dab tsi yog qhov txawv ntawm PS cov khoom thiab AS cov khoom ntawm cov khob dej yas

Cov ntaub ntawv dab tsi tam sim no siv rau cov khob dej yas hauv khw, xws li Tritan, PP, PPSU, PC, AS, thiab lwm yam PS tsis tshua muaj hais tias yog cov khoom siv rau cov khob dej yas. Kuv kuj tau ntsib nrog kev yuav khoom ntawm cov neeg siv khoom European. Tus editor tau nkag mus rau PS cov ntaub ntawv.
