Qhov txawv ntawm P355N thiab P355NH

Qhov sib txawv ntawm P355N thiab P355NH

Nov 27, 2025 Tso lus

Qhov sib txawv tseem ceeb yog lawv lub hom phiaj siv: P355N yog rau chav- cov ntawv thov kub, thaum P355NH yog cov hlau tsis zoo tshwj xeeb rau kev pabcuam kub. Thaum ob qho tib si sib koom cov khoom sib xws ntawm chav tsev kub, P355NH yog tsim los tuav lub zog thiab cov khoom ntawm qhov kub siab dua, ua rau nws tsim nyog rau kev siv xws li cov hlab ntsha hauv qhov kub thiab txias.
