I write this for embroidery machine buyers, if want to find china products and china suppliers, it maybe a good chioce for you to find a china business direcotry.
From the china online businesss directory, or just from google search engine, you can find many companies. you don't need to register, don't need to pay anything, you can search the product you want and get the all contact info of companies.
You need to check their profile and ask more question to make sure you find a quality suppliers.
Hope you do great business!
