Perhaps you should try some spelling variations:
hyoung kee » yong kee
chang hai » chang ha, shang hai, change has
yan guan » gan guan, yan yuan, yang guang
ying jin » yang jin, jing ji
yang jie » yang jin, yang di, yang jui
yan tan » tan tan, yan clan, yan wang
wang » wing, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or wan) hyoung kee ((yan tan) OR (yan guan)) ((ying jin) or (yang jie)) chang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) hyoung kee ((yan tan) OR (yan guan)) ((ying jin) OR (yang jie)) chang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) hyoung kee ((yan tan) OR (yan guan)) ((ying jin) or (yang jie)) chang hai ;*".
