2. Q: What advantages do you think compared with those companies who are manufacturers themselves?
A: We bring in international mind in communicating with worldwide customers, processional operation, which most of manufacturers don’t have. We are in the same city, same area with world famous company – , have many exchanges and interacts among advanced philosophy and idea.
Most of our manufacturers lack of international sales people for international business, even they have good products. They normally located in industrial area of small towns, or far away places to cities. Not easy to have professional staff with advanced mind. Even when staff working some years and become professional they would prefer to leave factory area in industrial places for working in big cities….It’s a headache of most of our manufacturers in China.
We provide professional service but very small margin for keep running, manufacturers if high professional people they have to give high salary or commission to staff, which is same to export through us leaving a little margin surviving, and we’ re more stable.
