Perhaps you should try some spelling variations:
yang yang » wang yang
chan kang » chung kang, chan eng, chan fong
zhong lan » huong lan, zhong tai
anhang 2 » anhang 1, anhang a, anhang i
chang 2 » chang _, chang c, chang ha
yang i » yang di, yang xi, yang yi
i lee » ii lee, i le, i les

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yang) OR (wang yan))) OR (chan kang)) yang i lee ((chang 2) OR (anhang 2)) zhong lan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) or (wang yan))) or (chan kang)) yang i lee ((chang 2) OR (anhang 2)) zhong lan ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (wang yan))) or (chan kang)) yang i lee ((chang 2) OR (anhang 2)) zhong lan ;*.
