Kholwa ukuba uninzi lwabahlobo bonke bathenge imela ekhitshini okanye babone imela ekhitshini, kodwa ukuveliswa kwentsimbi yentsimbi kuya kubhideka, le nto ilungile?
Yintoni le nto?
Ingaba yintsimbi engatyiwayo?
Okanye intsimbi?
Sukuba nexhala, make up encinci kuwe kuqala ukwazisa intsimbi yechrome (
cr)
, Umahluko phakathi kwempahla eyomileyo eyalandelayo.

Emva konyango lokucima ioli, ubunzima bunokufikelela kuma-54 -

Iimpawu zemveliso yentsimbi: ibukhali, i-Yi Fu yokugaya, akukho lula ukugqwala.

Iimpawu zemveliso yentsimbi: ibukhali ngakumbi, umhlwa kunye nokuqina, akukho lula ukuphuka, ilungile ngakumbi, i-Yi Fu yokugaya ingqolowa.
