Pamusoro pane "chii chinonzi chidimbu chemarasha uye kushandiswa kwayo?"Ndinovimba ndinogona kukubatsira.Kana iwe uchida kugona zviri mukati mezvimwe zvicherwa zvemigodhi, unogona kuterera kune ino webhusaiti, asi zvakare bvunza yedu yepamhepo vatengi sevhisi, tinoita zvatinokwanisa kuti tikushumire.
