Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
huang min » huang bin, huang lin, huang jing
yan clan » das clan, yan guan, yan yuan
clan hua » tan hua, tuan hua
hong hai » zhong tai, dang hai, hong tan
nan yan » nan ya, wang yan, qian yan
hsin » sin, hin, hein

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan clan hua hsin huang min ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yan clan hua hsin huang min ((hong hai) OR (shang hai)) ;*.
