Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wang yang » wang yan, wang liang, wang yanling
pei gang » wei guang, der gang, ii gang
pei yang » wei yang, hui yang, pei yun
3 longer » _ longer, 3 langer, a longer
2 longer » _ longer, a longer, 2 langere
tan hua » tuan hua, wang hua, tan chia

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: ((wang yang) OR (yang liang)) tan hua ((pei gang) OR (pei yang)) ((3 longer) OR (2 longer)) do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang liang)) tan hua ((pei gang) OR (pei yang)) ((3 longer) or (2 longer)) do ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang liang)) tan hua ((pei gang) OR (pei yang)) ((3 longer) or (2 longer)) do ;*.
