Perhaps you should try some spelling variations:
yang wang » yang yang, yan wang, yang guang
yan guan » gan guan, yan yuan, yang guang
hui yang » hui ying, du yang, h yang
6.2 long » 3.2 long, 3.1 long
tan hua » tuan hua, wang hua, tan chia
yi gang » ii gang, i gang, li gang
3 long » a long, 3.2 long, 3.1 long

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang wang) OR (yan guan)) tan hua ((yi gang) OR (hui yang)) ((6.2 long) OR (3 long)) d ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang wang) OR (yan guan)) tan hua ((yi gang) OR (hui yang)) ((6.2 long) OR (3 long)) d ;*.
