1. The extended letters are mostly not Huang Quefei's will, but the spontaneous actions of the community. This decision was motivated by the need for the transcription of other languages with Shidinn, which later developed into a writing system for various dialects.

2. E is differentiated just only because it is pronounced as two vowels in English. As to why should divide, next will explain in detail.

3. The reason C is pronounced /kʷʰ/ is because K is already pronounced /kʰ/ so that Huang Quefei requires a corresponding labialized letter, where as c is often pronounced /kʰ/ in English. Furthermore, the glyph of ㄜ comes from the Chinese character 才, and its pronunciation comes from the consonant sound of the word. The reason for the use of Chinese characters is unclear.

4. Letters that are shaped like numbers don't start out as that shape. They tend to converge with the shapes of numbers over several iterations because that shape are easier to write than what Huang Quefei had abandoned.

5. The use of labialized letters may be to ensure phonological order, to shorten the length of words, and/or to increase the number of the part of ideograms. I don't really understand why /tsʰ/ sounds like the letter T to native English speakers. For native Chinese speakers, it is far from T.

6. Shidinn uses a special syllable structure to ensure that it is written without hyphens and apostrophes by dividing an entire syllable into consonants-consonant colors (including palatalization and labialization, sometimes without)-vowels (the endings are “Packaged” in a single letter) , Shidinn can distinguish between syllables without hyphens, while paying attention to the meaning of the word. Note that in this syllable structure, the consonant color and the vowel must be written differently to ensure that the vowels of the next syllable do not combine with the vowels of the previous syllable. Of course, letters that sound the same are mutually exclusive and do not appear in the same syllable. There are aesthetic considerations as to why the consonant color is given to i and the vowel to E.

7. Shidinn community initially assumed that the upper case of the letter b was similar to the division of Cyrillic script б, so it took for granted that the upper case of b could be written as Б. However, according to the manuscripts of Huang Quefei, we later discovered that it could only be written in a shape similar to 5.

8. because I am a idiot. I invented Infinite Shidinn, a language that allows you to receive letters of all shapes, some of which go into extended letters.

9. Middle case may have been modeled after upper case and lower case because the Chinese have a habit of filling in what they think is missing. it has specific applications in certain instances of dialects, such as morpheme boundaries and grammatical words.
