Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang, yan guan
you liang » you xian, you liangzhi
tuan hua » tuan vu, yuan hui
pei yang » wei yang, hui yang, pei yun
tan hua » wang hua, tan chia, tan puay
di long » i long, de long, ii long
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 (you liang))) OR (yang guang)) ((tuan hua) OR (tan hua)) pei yang di long du ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang liang) or (you liang))) or (yang guang)) ((tuan hua) or (tan hua)) pei yang di long du ;*.
