The best work I have seen is the "50感懷” by NewVoice. Besides the easy flow of the composition and the depth of thought conveyed, what impresses me the most is how closely the writer resembles the native speakers in the logic and the manner of presentation. It usually doesn't take more than a brief glance to find many language problems in a work posted on this forum, but I had to read very attentively to only find some possible defects.
