What you want to ask is what does the girl's signature on WeChat mean? The meaning is as follows:

"Look at which page is messed up by the wind" is a visual statement. The original meaning means that when reading a book in the wind, the pages will be blown and some pages will be skipped because of the different strength of the wind, so you should look at which page according to which page the wind blows. This metaphor also implies a flexible way of thinking, not sticking to a fixed plan or scheme.
