why is the price of china products more cheaper in the world ?

hmm... i think it is because labor is cheap there and there are a lot of factories which allow them to mass-produce their products... also, competitions among the factories force them to lower their prices...

Chines are doing home made works, they are very confidenc in their work...

Low labor and production costs because of a dominated marketplace and price controls

it is mainly because of cheap labour and due to their currency their currencey is nor that stong in international market and they have huge population so it is of cheaper labour, and good manufacturing technology.

probably you allready know that the laber is cheap because there so many and the conpetition for a job is so great that they are willing to lower their income then have none at all. so all the firms profit and whit cheaper laber comes cheaper products. But the quality is not that great because they produse a lot in a very short time.
