What is a basketball cross step? What's the difference between ordinary direct layups? I hope you don't copy and paste, but explain it in your own easy-to-understand words.

Basketball cross step is a lateral moving method. Take moving to the left as an example to illustrate: the right foot pushes the ground hard, the body center of gravity moves to the left foot, the right foot falls to the left side of the left foot, and then the body center of gravity moves to the right foot, and the left foot steps to the left. This is a cross step. The biggest difference between the two is that forward layup is moving towards you, striding is moving horizontally to the left or right, striding is defensive footwork, and forward layup is a normal scoring method.
