In novels, numbers were usually used to represent the size of the red packet. The exact size of the number depended on the reader's age, status, wealth, and other factors. For example, a young reader might receive a smaller red packet and an older reader might receive a larger red packet. In some novels, there might be situations where numbers were used to represent the amount of money in the red packet. For example, a red packet contained 500 yuan, a red packet contained 1000 yuan, and so on. Therefore, the exact number to use to represent a good character depended on the plot and setting of the novel.
