One-stroke signature of Chinese characters is a challenging calligraphy skill. On the basis of the conventional Chinese writing method, this signature omits some strokes and represents a "country" in a concise form, which can be expressed as follows:

1. Write a "k" first. This "K" is the upper part of the word "Guo" and occupies the upper horizontal position of the word "Guo".

2. Write an "L" under "K". This "L" is the left half of the word "Guo" and occupies the left vertical position of the word "Guo".

Write an inverted "u" under "l". This "U" is the right half of the word "Guo" and occupies a vertical position on the right side of the word "Guo".

Finally, write a "one" under "U". This "one" is the last stroke of the word "country", occupying the middle of the word "country".

Through such steps, you can write a concise and artistic signature of the word "country". Of course, it takes more practice to master it skillfully.
