I'm an industrial designer in China, my wife is Chinese. She works in sourcing and B2B sales.
My wife will help me find the manufacture you need. We will also help with samples.
I will need a lot more information about your product. Such as quantity, target price and your design.
Please note it is Chinese new year soon, so the whole country is shutting down, it very hard to contact manufactures at the moment, you need to wait to after Chinese new year.
