Very helpful. I tell myself to come back here so to learn more for my calligraphy. Thank you.

I accepted with your opinion that Chinese characters is beautiful handwriting that look so beautiful and it meaning full.

As I mentioned, most of the Chinese characters order follow the rule: up to down, left to right. For the character 華, the right order is that H.K. based APP. Since the middle part is constructed by 十 十， not just 艹.
Regarding 说文解字，you should first know the word-making radical, then base on it, search the character you want to check. For example, 元， its word-making radical is
一， then you can turn to the 一 radical to find 元. There are 540 radicals there. 说文解字 only shows you the origin of each character. I can recommend you an online dictionary called 汉典, it`s easy to handle and very convenient.

Thanks for the relationship between 8 and 11.
I did not mean the two systems (simplified and complicated characters).
I try another time: please give the order of the compliated character flower: 華
What is the number of strokes (not counting the grass radical)
My android keyboard needs seven. 一丨丨
一一丨丨一一丨
A H.K. based App for Chineae stroke orders tells me 8.一丨丨
一丨一丨一一一丨
You see?
And yes you are very right: 說文解子 is not easy to handle.
That is why I was asking (Chinese people). I have never found how to use it in detail.
That is what I am looking for.
Hope, you can help me further

Hi! Firstly, the 11 basic strokes are the most commonly used strokes in every character. The 8 Yong Principle is a kind of method to help the learners master how to write the strokes very well. All the 8 strokes are basic strokes, thus some people learn to write calligraphy by practicing 永 as a start.
The difference of writing system between Mainland China and H.K. is one is using simplified Chinese characters, the other is using traditional version. Quite a number of characters are written differently. Generally speaking, almost of the characters in both versions are written in this sequence: 从上到下，从左到右。
说文解字 is not easy to use. You should first know the traditional Chinese characters and the classical style of writing. It shows you the origin and developing process of the characters and related researches.

Of course, it helps to remind people that “stroke order” is extremely important in *every* writing system, not just those written in ideographic characters. Just imagine what a person’s handwriting would look like in languages written in alphabets if they tried to write their letters completely differently than the “accepted”, “conventional” manner – it looks just as “crazy” or “pen inserted down” as it does in character-based writing systems. 😉 Even “correct” handwriting is distinctive, when written by left-handed people, and is easy to recognize for what it is when one understands the fundamental differences between it and right-handed writing.

In theory, stroke order would not matter in any language, if a person were capable of literally reproducing letters or characters as simple “pictures”, but of course very, very few people have that kind of skill and so for the rest of us, the specific order/manner in which we write them all makes an enormous difference in their final appearance!
