Perhaps you should try some spelling variations:
sang yung » kang young, song byung, sung myung
yung chen » yun chen, yu chen, yulu chen
shang kai » shang hai
tan ying » fan ying, ran ying, tan yang
jin ying » li ying
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
yang yi » yang di, yang xi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tan ying) or (jin ying)) sang yung chen ((((yang jin) OR (yang jun))) or (yang yi)) shang kai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tan ying) OR (jin ying)) sang yung chen ((((yang jin) OR (yang jun))) OR (yang yi)) shang kai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tan ying) or (jin ying)) sang yung chen ((((yang jin) OR (yang jun))) or (yang yi)) shang kai ;*".
