Zapamwamba Kwambiri En 10219 S235jrh

Chithunzi Chodziwika Kwambiri cha En 10219 S235jrh

Kufotokozera Kwachidule:

Zogulitsa zathu zimagwirizana ndi miyezo ya ku Europe ndipo zimakhala zozizira, sizifuna kutentha kwambiri, zomwe zimaonetsetsa kuti zimakhala zolimba komanso zolimba. Gulu la S235JRH limadziwika chifukwa cha kusinthasintha kwake komanso kupangika bwino, zomwe zimapangitsa kuti likhale labwino kwambiri pakugwiritsa ntchito kapangidwe kake komwe kudalirika ndi magwiridwe antchito ndizofunikira kwambiri.
