Chen Long, an international Interpol officer from Huaxia, was set to retire in a year. After a lifetime of hard work, his greatest wish was to spend time with his daughter. This trip to the United Kingdom was a rare vacation before his retirement, coinciding with his daughter's birthday. He planned to leave from Hong Kong to celebrate with her.
At the airport lounge, Chen Long's phone suddenly rang. Upon looking, he saw it was from an unknown number. If it were a Huaxia number, Chen would assume it was an advertisement and wouldn't answer. However, this number was from the United Kingdom.
Out of caution, Chen Long answered the call.
"Is this Detective Chen Long?" said a man's voice on the other end, speaking fluent Huaxia.
Chen Long replied, "Who are you, and how do you have my number?"
