@nmaheshwari,

There are five strokes of the character 正, so some Chinese people like to mark numbers using it. For example, if you are counting how many people come into a restaurant,you can write down one stroke of 正 when one person enters. When you finish one 正, it means there are 5 people get in, then you can start another 正. When you are done, you just need to count how many 正 you write, then you can tell how many people are in the restaurant.
