Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
you liang » you xian, you liangzhi
wong yue » hong yu
wang yue » wang hua, wang yan, wang he
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 d, long du, longer do

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((you liang) or (yang guang)) tan hua pei ((((wong yue) OR (wang yue))) or (yang y.c)) long do ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((you liang) OR (yang guang)) tan hua pei ((((wong yue) OR (wang yue))) OR (yang y.c)) long do ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((you liang) or (yang guang)) tan hua pei ((((wong yue) OR (wang yue))) or (yang y.c)) long do ;*".
