How to write cross hook?

The font on the computer and its dictionary is mainly Song style, with no obvious tick, but let's change the font (Song style is above, italics are below):

This is obvious, obviously a "cross-folding hook".

The font is square, the strokes are horizontal and vertical, the thickness is clear, the edges and corners are sharp, rigorous, neat and even, and the strokes are regular, which makes people feel comfortable and eye-catching when reading. But for writing, Songti is not a good font, and it has no taste of traditional calligraphy at all. Therefore, when teaching, most students choose regular script to teach.
