Little Red Book app has many note editing skills. Here are some common techniques:

1. Paragraph content should not exceed 3-5 lines. Use blank lines or symbols such as ","to increase the "sense of block" in copying and typesetting.

2. The number of words in the little red book notes is limited to 1000 words, so pay attention to the number of words when writing.

3. The picture of each little red book note, plus the cover picture, can be put in a * * * at most 9. So when arranging the content, you can also see if your language is concise and to the point, otherwise there will be too much content and not a single note.
