Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
der longue » de longue, very longue, hertz longue
yan guan » gan guan, yan yuan, yang guang
tuan hua » tan hua, tuan vu, yuan hui
wei yang » wei wang, wei yang's, wei shang
pei yang » hui yang, pei yun, yi yang
de long » le long, de longue

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: ((yang liang) OR (yan guan)) tuan hua ((wei yang) OR (pei yang)) ((de long) OR (der longue)) do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yan guan)) tuan hua ((wei yang) OR (pei yang)) ((de long) or (der longue)) do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yan guan)) tuan hua ((wei yang) OR (pei yang)) ((de long) or (der longue)) do ;*.
