Perhaps you should try some spelling variations:
jeang yean » jeong yeon
wang liang » wang yang
wang wang » wang yang, wang yan, wang yong
law main » law pain, law making, new main
xi test » ai test, i test, ii test
han min » han men, kan min, chan ming
yan xi » yang xi, yan zi

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang wang) OR (wang liang)) yan xi test ((law main) or (han min)) jeang yean ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang liang)) yan xi test ((law main) OR (han min)) jeang yean ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang liang)) yan xi test ((law main) or (han min)) jeang yean ;*".
