Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan liang » yang liang, wang liang, you liang
wong yue » wang yue, hong yu
yang y.c » yang yi, yang yao, yang 4.3
tan hua » tuan hua, wang hua, tan chia
hua pei » hua wei
long do » long du, longer do, long ago
long d » long du, 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: ((yan liang) OR (yang guang)) tan hua pei ((wong yue) OR (yang y.c)) ((long do) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang guang)) tan hua pei ((wong yue) or (yang y.c)) ((long do) OR (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang guang)) tan hua pei ((wong yue) or (yang y.c)) ((long do) OR (long d)) ;*.
