This story was written in 2012. It is set in Hong Kong and tells the story of how the protagonist, who studies law from the Mainland to Hong Kong, adapts to the cultures of the two places. The festival stories, road shops and restaurants described in the story all existed at that time. Although the environment of Hong Kong has changed a lot in the past ten years, some of the restaurants and festival celebrations in the story still exist here today. As for the plot of studying and taking exams in the law department, it took half a year to collect information in order to make the whole story more three-dimensional. Today in 2024, many things may no longer exist, but looking back at the scene 12 years ago is like entering a time machine. Hope readers like it.
