Frequently Asked Questions

I am a first-time buyer, how do I start ?

First of all, welcome to our website and many thanks for your great interest!

Contact us via email or telephone, we will provide you a free consultation about what and how you can do. Sleep on it, come back to us anytime whenever you are ready.

What makes you different than other manufacturers ?

Projecting confidence is almost like an instinct, whenever this question is asked, you will normally get an answer like this: "We are the best in the industry! The rest is just not as good."

However, we differ ourselves from other manufacturers by emphasizing on communication (the fancy version would be - by emphasizing on cultural management). Understanding differences is the fundamental of communication, it allows us to align our perspectives and to achieve the result we actually expected.

A simple example, in Ireland, number 4 represents luck as it symbolizes the 4-leaf-clover. As in China, number 4 is being avoided in almost everywhere as the tone of 4 sounds similar to death. So, if without the awareness of differences, can you imagine how it would go when two businesses from different cultural background get together and start discussing about their goal? We will let you draw your own conclusion.

What languages do you speak ?
