Zhi-Gin, who was born in Germany to a Hong Kong father and German mother, has broken into the HSV line-up in recent weeks during Rodolfo Cardoso's interim period in charge of the team.
Newly appointinted Hamburg coach Frank Arnesen said the 20-year-old, who is known in Germany as "Andreas," made a "dream debut" in his maiden appearance for the club in last month's 2-1 win over Stuttgart.
Zhi-Gin's progress has prompted interest the associations of China and Hong Kong. However Goal.com spoke to his uncle, Peter, who said the Hamburg born and bred youngster's international preference would be to play for Germany.
"He couldn't and doesn't want to play for Hong Kong. His wish is one day he could play for Germany, which is his birth place," Peter said.
"Although his father is from Hong Kong, he is not Cantonese. He came to Hong Kong about 10 years ago, but made no contact with the Hong Kong football.
"Hong Kong made a bigger impression on him for shopping than football."
When asked if the German national team had contacted Zhi-Gin, Peter said they had not but added that was natural given he's only just begun his Bundesliga career.
"As far as the German national team is concerned, they have not yet contacted him. This will take some time. After all, he is still in the fledgling stage of his career."
Peter also revealed Zhi-Gin cannot speak Cantonese or Chinese and only German, and added that his nephew's favourite footballer is Cristiano Ronaldo.
