Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang, yan guan
y.c long » 3.2 long, 3.1 long, 2.2 long
tuan vu » thanh vu, tuan hua
tan hua » tuan hua, wang hua, tan chia
pei yun » lei kyun, mei yung, pei yang
yun y.c » yang y.c
long du » long d, long do, long run

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 (tan hua)) pei yun y.c long du ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang guang)) ((tuan vu) or (tan hua)) pei yun y.c long du ;*.
