As far as I know, Egyptian writing is not only written from right to left, but can also be written from left to right and top to bottom. The sign that determines whether it is from left to right or from right to left is the symbol in the text itself that is not axially symmetrical. For example, if there is a symbol that looks like a bird, it can be used to determine. If the bird's head points to the left, it means moving from left to right, and vice versa. When writing from top to bottom, there are vertical lines between each column, making it easier to judge.
