Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang, yan guan
tuan hua » tan hua, yuan hui
pei yang » wei yang, hui yang, pei yun
yang 3.2 » zwang 3.2, yang 4.3, yang y.c
tuan vu » thanh vu
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang liang) OR (yang guang)) ((tuan vu) OR (tuan hua)) pei 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 guang)) ((tuan vu) or (tuan hua)) pei yang 3.2 ((long d) OR (long du)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang guang)) ((tuan vu) or (tuan hua)) pei yang 3.2 ((long d) OR (long du)) ;*.
