Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
tuan china » wuhan china, can china, taiwan china
longer do » longer _, longer a
yan wang » yuan wang, yang yang, qian wang
jaan hui » yuan hui
pei yang » wei yang, hui yang, pei yun
yang de » yang di, rang de, yang d
long do » long d, long du, long ago

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)) ((jaan hui) OR (tuan china)) pei yang de ((long do) OR (longer do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (yang guang)) ((jaan hui) or (tuan china)) pei yang de ((long do) OR (longer do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (yang guang)) ((jaan hui) or (tuan china)) pei yang de ((long do) OR (longer do)) ;*.
