The protagonist Ah Hai seized the opportunity when the special zone was established and transformed from a hawker who smuggled electronic watches to a regular merchant, during which he insisted on studying at night school. This setting can not only show the characteristics of the era of rampant smuggling, but also reflect business wisdom through the upgrade of "water customers-counter-shops". The details of night school reading exactly echo the learning theme. Era: The background of the story has a strong color of the times. The content is mainly about family life, learning to start a business, and counterattack in life. The golden finger does not play a major role in the plot. It is intended to reflect the protagonist's hard work and wisdom in rewriting life in a specific era.
