What does it mean to write Zhengzi on the butt?

If the word "zheng" is tattooed on the body, it is possible that the person has gone through detours (crooked) and is determined to correct evil and return to the right path. He should always remind himself to do the right thing and return to normal. Or maybe you simply like straight characters and get a tattoo with this character. Some things are difficult to explain clearly without personal experience.

Zhengzi is also a tool word used by Chinese people for counting. The orthographic characters have five strokes and are simple and easy to write. A complete straight character represents 5 numbers, which is usually used in elections to count votes. The final number multiplied by 5 is the number of votes someone has. But they were all written on the blackboard, and no one wrote them on their bodies.
