A Letter of Thanks

Last month, I received a diploma of Ezine Articles. I am writing this letter to thank editors of Ezine Articles for their earnest help to modify my “Lung cancer cases linked to air quality! What's the solution to that?!”.

By repeatedly amended, my article approved in the end.

In future, I will be in constant progress, constantly enrich, explore potential, get progress and mature constantly. I will make a contribution to protecting our environment with continuous commitment to research and design my HHO Carbon Clean Machine.

Faithfully Renhua Huang
