What should I do to add some materials to the National Day celebration?

If you add one more dot to the clear word, it will become a typo. Chinese characters in China are square characters, which are composed of dots, vertical lines, horizontal lines, apostrophes, apostrophes and hooks. Some words can be changed into another new word by adding a little bit, a vertical line and a horizontal line. However, some words have a strict structure and cannot be added with a vertical line and a horizontal line, that is, they cannot be added with an extra stroke. This is the case with the word "Qing".
