I was taught to write in school (USA) by rotating the page about 15-30 degrees to get a more natural stroke. I actually find it difficult to write with the page completely square to my body.
I've been practicing Chinese characters off and on for years, and just today realized that I've been keep thing page square to myself, and that it's always felt a bit awkward, especially horizontal strokes. Today for the first time I decided to rotate the page slightly and it immediately felt more natural and efficient.
I was wondering if rotating the page is something that Chinese people do or are taught to do, or not.
I think I probably kept the page square because it helps me see the characters better. It was initially disorienting to rotate the page, but I'm going to experiment for a while to see if this can increase my comfort, and efficiency.
