Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan liang » yang liang, wang liang, you liang
losung do » losung d, losung des, losung der
tuan hua » tan hua, tuan vu, yuan hui
pei yang » hui yang, yi yang
wei yang » wei wang, wei yang's, wei shang
i losung » die losung, iii losung, i long
pei yun » lei kyun, mei yung, wei yuan

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 liang) OR (yang guang)) tuan hua ((((pei yang) OR (wei yang))) OR (pei yun)) i losung do ;~.
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang guang)) tuan hua ((((pei yang) or (wei yang))) or (pei yun)) i losung do ;*.
