Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan wang » yuan wang, yang yang, qian wang
tan chia » tuan china, than china, can china
pei yang » hui yang, pei yun, yi yang
wei yang » wei wang, wei yang's, wei shang
tan hua » tuan hua, wang hua, tan puay
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: ((yan wang) OR (yang guang)) ((tan hua) OR (tan chia)) ((pei yang) OR (wei yang)) a long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (yang guang)) ((tan hua) or (tan chia)) ((pei yang) OR (wei yang)) a long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (yang guang)) ((tan hua) or (tan chia)) ((pei yang) OR (wei yang)) a long du ;*.
