Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
yang guang » yan guan
yang yang » wang yang, wang yan
wei yang » pei yang, wei wang, wei yang's
yang 3.2 » zwang 3.2, yang 4.3, yang y.c
tan hua » tuan hua, wang hua, tan chia
long du » long do, long run, long did
long d » long do, long _, long 2

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang liang) OR (yang yang))) or (yang guang)) tan hua wei yang 3.2 ((long d) or (long du)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang liang) OR (yang yang))) OR (yang guang)) tan hua wei yang 3.2 ((long d) OR (long du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang liang) OR (yang yang))) or (yang guang)) tan hua wei yang 3.2 ((long d) or (long du)) ;*".
