Dear Mr. Guoxiang Kai,
We are exited to present you yet another TÜV certification of our products with the emission reduction certificate MATHY-BE and MATHY-D.
我们很兴奋的向您提供另一份TÜV 认证，是关于玛蒂BE和玛蒂D 节能减排方面的证书。
The use of MATHYBE / MATHYD every 3.000 km has been tested to reduce the emission significantly. We have a large demand in Europe for this product due to the particulate air polution in cities. This might apply to China as well.
