Sending a red packet to a scholar, what number is good?

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.
