The following is a general analysis of horizontal painting, not a master, just sharing, I hope I can help you!
First, there are three kinds of horizontal strokes: starting from the front, such as the bottom horizontal stroke of "Gai, Er"; The sharp pen entry (sharp horizontal) is a virtual pen entry, such as the bottom horizontal of "yellow"; Go straight, like a "big" cross.
Second, there are four kinds of horizontal pen collection: permanent pen collection, that is, pen collection without pressing the tail, such as horizontal pen collection at the bottom of the "cover"; Recycling is the same as other regular script, so this is no longer said; Swallowtail set, that is, official script set as long as it is "silent"; The other is a pen as sharp as "big"!
There are many other strokes, and you will understand them with more practice! Here are a few words I synthesized with photoshop for analysis, hoping to help you!
