Article Introduction：The key to implementing text surround images in Word is to correctly set the layout and surround methods of images. First, after inserting the picture, set its layout to "float above the text" or "below the text", and then select "tight type" or "four-circular type" through the "Picture Format" tab; then drag the picture to adjust the position, and fine-tune the size through the control points. If necessary, cancel the "lock mark" or set the "absolute position" to stabilize the layout; if the text is not surrounded, check whether the picture is embedded, whether it is in a table or text box, and whether the document view is "page view", and cancel the "Allow Word to adjust the position" to fix the picture position.
