If you are in China and you want to come and see us, let us know. (You can contact us in the normal way through this online ticketing system.)
Our offices are in the city of Shenzhen - it's the south city of China. You can come to Shenzhen from other cities easily.
You could pre-order some samples using the online system and collect them at our office without having to ship them.
We can show you samples of items we have in stock, but if you don't preorder samples we can't guarantee we have what you need if you want to take things away with you.
