Kushandiswa
Kusimudza nekusunga, kusimudza mitoro, kusunga mitoro
Semugadziri wecheni dzesimbi dzakatenderera kwemakore makumi matatu, fekitori yedu yagara ichishanda uye ichishandira nguva yakakosha yekushanduka kweindasitiri yekugadzira cheni dzesimbi muChina ichipa rubatsiro rwekuchera (kunyanya mugodhi wemarasha), kusimudza zvinhu zvinorema, uye zvinodiwa zvekutakura zvinhu mumaindasitiri pamacheni esimbi akatenderera ane simba guru. Hatigumiri pakuva mugadziri wecheni dzesimbi dzakatenderera dzinotenderera muChina (dzine huwandu hwematani anodarika 10,000 pagore), asi tinoomerera pakugadzira zvinhu zvitsva uye kuvandudza zvinhu nguva dzose.
