Replying to [Admin]: We are an inspection company located in Hong Kong owned and operated by US and UK citizens. We find and see the problems every day, and here's how we would summarize the situation:
China is the factory of the world, everyone knows that, including the Chinese themselves. The majority of problems we find are due to carelessness and oversight, not because any Chinese suppliers are trying to cheat or con their clients. Ofcourse, there are the odd scammers here and there, and this goes for any country, not just China.
If customer A is not willing to place an order next time, there's customer B, C and D already in line to place their order, so what if there's a broken edge or a scratched screen or even a few pieces short? <---- It's this type of attitude which is causing problems for the end buyers, and for which many clients come to us. When the mainland suppliers know you have a presence in HK or China, and your rep can come for an inspection at anytime, then the suppliers actually pay much more attention to the details which they normally overlook.
Being in this business, I can honestly conclude that chinese people are some of the most hard working people I have ever come across, but in the same way that you wouldn't trust your baby to just any babysitter, you should also closely monitor, guide and educate your suppliers in order to help support your future business with them.
Good luck
