What is the content of Dongguan calligraphy?

Return to my Dongguan calligraphy as shown in the figure below:

"Give me back Dongguan" refers to an anti-crime activity that took place in Dongguan City, Guangdong Province, China on September 23, 20 15. At that time, the local public security department launched a concentrated crackdown on underworld organizations and evil gangs, arrested a number of criminal suspects, and announced the slogan of "Give me back Dongguan". This action has attracted wide attention and has become an important measure to eliminate evils in Chinese mainland.

Dongguan calligraphy is a calligraphy style that originated in Dongguan, Fujian Province. Its calligraphy features are "tough strokes, prominent strokes, complete structure, strokes like knives, with a certain sense of lack". Its calligraphy is characterized by "vigorous and powerful, atmospheric modeling", paying attention to the strategy of strokes, and the font is relatively large, which can clearly express the meaning of words.
