Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
than china » tuan china, han china, wuhan china
yang yang » wang yang
hui ying » huei ying, hoi ying, hui ping
3.2 long » 3.2 land
yi yang » yin yang, yi gang, yu yang
long d » long do, long du, long _

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang yang) OR (wang yan))) or (yang guang)) than china ((yi yang) or (hui ying)) 3.2 long d ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yang) OR (wang yan))) OR (yang guang)) than china ((yi yang) OR (hui ying)) 3.2 long d ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) OR (wang yan))) or (yang guang)) than china ((yi yang) or (hui ying)) 3.2 long d ;*".
