Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
zwang 3.2 » zwang 2.2
tuan hua » tuan vu, yuan hui
yang 3.2 » yang 4.3, yang y.c
tan hua » wang hua, tan chia, tan puay
long do » long d, long du, longer do

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 liang) OR (yang yang)) ((tuan hua) OR (tan hua)) pei ((yang 3.2) OR (zwang 3.2)) long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yang yang)) ((tuan hua) or (tan hua)) pei ((yang 3.2) OR (zwang 3.2)) long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang yang)) ((tuan hua) or (tan hua)) pei ((yang 3.2) OR (zwang 3.2)) long do ;*.
