The alphabet writing system is based on some principles as follows:

1. Because a single line that is too long can make it difficult to recognize its length, each symbol will include a vertical line and there will not be a single vertical line occupying 3-grid distance without horizontal cutting.

2. A symbol must contain a vertical or horizontal stroke in the bottom block to avoid the appearance of two letters with the same appearance but different heights.

3. Due to the vertical line being read first to distinguish different letters before reading the horizontal line, the horizontal line in a letter always starts to the right of the vertical line.

4. In lowercase letters, voiced consonants are always one vertical line higher than clear consonants.

5. The size of vowels is always smaller than that of consonants.

6. Generally, the more commonly used the consonants are, the simpler they are. 

7. Letters with more similar pronunciations usually are more similar, such as corresponding voiced and clear consonants, h and f, w and u, y and i, m and n.

8. Letters and numbers can be distinguished by the bottom two strokes.

9. Add a horizontal stroke above the corresponding lowercase letter for uppercase letters.
