The stroke order of the word "Nie" is as follows:
1. From top to bottom, from left to right, write some horizontal pictures first, and then write some vertical pictures to form a basic structure of "T".
2. Then, write oblique strokes from the middle to the lower right to form oblique strokes.
3. Finally, write another stroke from the top left to the bottom right to form an oblique hook.
Please note that different calligraphy styles and personal habits may be slightly different. The above is the common stroke order of Nie characters. If more accurate and standardized stroke order is needed, it is recommended to refer to professional dictionaries or calligraphy textbooks.
