Well, in English, you always write from left to right.
But, in Chinese, we may write from left to right, from right to left as well as "from up to down",
like these characters on the top right corner here:

But I'm sure "from up to down" must be incorrect English.
How can I express this in English then?
Also, "from left to right", "from right to left", etc. sound rather colloquial.
Is there a more formal way to say it?
May it be something like "vertical writing", "horizontal writing", "lateral writing" or.....?
How can I express this writing direction thing?
