Kwiveki ephelileyo, ikamva lesinyithi se-ferrous metal saseTshayina libonise ukunyuka ngenxa yempembelelo yokukhula kwemarike yesitokhwe. Okwangoku, ixabiso kwimarike yokwenyani nalo linyukile kwiveki yonke, nto leyo ekugqibeleni ikhokelele ekunyukeni kwamaxabiso epayipi engenamthungo ikakhulu kwiSithili saseShandong naseWuxi.

Ekubeni uluhlu lweepayipi ezingenamthungo luyekile ukukhula emva kokwanda okuqhubekayo kweeveki ezi-4, kwasetyenziswa eminye imigca embalwa yemveliso. Nangona kunjalo, ixabiso eliphezulu lezinto ezisetyenzisiweyo linokunciphisa inzuzo yeefektri zeetyhubhu zentsimbi.

Ngokwengqikelelo, kule veki ixabiso letyhubhu yaseTshayina elingenamthungo kwimarike lisaza kuhlala lizinzile kwaye lisenokunyuka kancinci.
