Amapayipi akhanyayo angahlala kanjani isikhathi eside
ngumlawuli ngomhlaka-20-10-30
Eqinisweni, umkhiqizo ngamunye wokushisa kagesi unesikhathi sawo sokusebenza. Imikhiqizo embalwa yokushisa kagesi ingafinyelela iminyaka engaphezu kweyi-10. Kodwa-ke, uma ishubhu elikhanyayo lisetshenziswa futhi ligcinwa kahle, ishubhu elikhanyayo lihlala isikhathi eside kunelejwayelekile. Vumela uXiao Zhou akutshele lona. , Indlela yokwenza i-radian...
