1. The Chinese character "Han" can be designed to use a smooth curve in the center to show the elegance and fluidity of the Chinese character "Kou". This curve can start from the upper left corner of the mouth, pass through the center of the mouth, and then move smoothly to the lower right corner of the mouth. The length and angle of this curve can be fine-tuned to adapt to the rhythm and beauty of the whole signature.

2. The "ten" part of the word "Bo" can be designed as a horizontal line, which can be slightly bent to increase the dynamic of the signature. The "inch" part of the word "Bo" can be designed as a diagonal line in the upper left corner, which can be slightly bent to increase the dynamic and interesting signature.

This design not only retains the structure of Chinese characters, but also endows the signature with fluidity and interest. Of course, this is only a suggestion, and you can adjust it according to your personal preferences and needs.
