When I write this kanji radical, how do I know when I should write the horizontal lines inside the outer part first or write them after? This radical is in many kanji, and I am trying to find a pattern so I can remember the correct order. For example, the stroke order in all these kanji are different:
用 (horizontal lines first)
角 (vertical line first)
通 (horizontal lines first)
What is the general pattern if it was put into words? Is it that if the vertical line is longer, then the horizontal line's are first, and vice versa otherwise? Also, how do I know when to make the vertical line go past the horizontal ones? Is this kanji: 角 the only kanji without a long vertical line out of all the kanji that have this radical?
