Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
thin jeng » thin end, thin lens
jeng dong » eng hong, zeng doug
ii first » ai first, 2 first, 3 first
dong bin » dong sin, dong di, dann bin
i first » ai first, 2 first, 3 first

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

• Performing a fuzzy search may retrieve terms with similar spellings: wing ((yang yang) or (wang yang)) ((i first) OR (ii first)) thin jeng dong bin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((yang yang) OR (wang yang)) ((i first) OR (ii first)) thin jeng dong bin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yang yang) or (wang yang)) ((i first) OR (ii first)) thin jeng dong bin ;*".
